Major problems are being experienced in human medicine from antibiotic resistant bacteria. Moreover, no new chemical class of antibiotics has been introduced into medicine in the past two decades. The aim of the current study presents experimental results that evaluate the capability of bio surfactant rhamnolipid on enhancing the efficacy of hydrophobic antibiotics. Serial dilutions of azithromycin and clarithromycin were prepared. A bacterial suspension (approximately 5 X 105 CFU) from an overnight culture in MSM was inoculated into 20 ml sterile test tube each containing a serial 10-fold dilution of the test antibiotic(s) in broth with or without 200 mgL-1 rhamnolipid. The tubes were incubated for 24 h with vigorous shaking at 37°C. Antimicrobial activity in multiple antibiotic-resistant gram-negative bacteria pathogens and gram-positive bacteria were assessed using optical density technique. The results clearly demonstrated that the presence of rhamnolipid significantly improved the efficiency of both antibiotics. We hypothesized that the addition of rhamnolipid at low concentration, causes release of LPS which results in an increase in cell surface hydrophobicity. This allows increased association of cells with hydrophobic antibiotics resulting in increased cytotoxicity rates. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydrophobic%20antibiotics" title="hydrophobic antibiotics">hydrophobic antibiotics</a>, <a href="https://publications.waset.org/abstracts/search?q=biosurfactant" title=" biosurfactant"> biosurfactant</a>, <a href="https://publications.waset.org/abstracts/search?q=rhamnolipid" title=" rhamnolipid"> rhamnolipid</a>, <a href="https://publications.waset.org/abstracts/search?q=azithromycin" title=" azithromycin"> azithromycin</a>, <a href="https://publications.waset.org/abstracts/search?q=clarithromycin" title=" clarithromycin "> clarithromycin </a> </p> <a href="https://publications.waset.org/abstracts/16898/efficacy-enhancement-of-hydrophobic-antibiotics-employing-rhamnolipid-as-biosurfactant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16898.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">515</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">480</span> A Review on the Use of Herbal Alternatives to Antibiotics in Poultry Diets</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sasan%20Chalaki">Sasan Chalaki</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Ali%20Mirgholange"> Seyed Ali Mirgholange</a>, <a href="https://publications.waset.org/abstracts/search?q=Touba%20Nadri"> Touba Nadri</a>, <a href="https://publications.waset.org/abstracts/search?q=Saman%20Chalaki"> Saman Chalaki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the current world, proper poultry nutrition has garnered special attention as one of the fundamental factors for enhancing their health and performance. Concerns related to the excessive use of antibiotics in the poultry industry and their role in antibiotic resistance have transformed this issue into a global challenge in public health and the environment. On the other hand, poultry farming plays a vital role as a primary source of meat and eggs in human nutrition, and improving their health and performance is crucial. One effective approach to enhance poultry nutrition is the utilization of the antibiotic properties of plant-based ingredients. The use of plant-based alternatives as natural antibiotics in poultry nutrition not only aids in improving poultry health and performance but also plays a significant role in reducing the consumption of synthetic antibiotics and preventing antibiotic resistance-related issues. Plants contain various antibacterial compounds, such as flavonoids, tannins, and essential oils. These compounds are recognized as active agents in combating bacteria. Plant-based antibiotics are compounds extracted from plants with antibacterial properties. They are acknowledged as effective substitutes for chemical antibiotics in poultry diets. The advantages of plant-based antibiotics include reducing the risk of resistance to chemical antibiotics, increasing poultry growth performance, and lowering the risk of disease transmission. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=poultry" title="poultry">poultry</a>, <a href="https://publications.waset.org/abstracts/search?q=antibiotics" title=" antibiotics"> antibiotics</a>, <a href="https://publications.waset.org/abstracts/search?q=essential%20oils" title=" essential oils"> essential oils</a>, <a href="https://publications.waset.org/abstracts/search?q=plant-based" title=" plant-based"> plant-based</a> </p> <a href="https://publications.waset.org/abstracts/178978/a-review-on-the-use-of-herbal-alternatives-to-antibiotics-in-poultry-diets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/178978.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">77</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">479</span> Optimal Temperature and Time for Lactic Coagulation of Milk Containing Antibiotic: Evaluation of Yogurt Fermentation Parameters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arezoo%20Ghadi">Arezoo Ghadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Adonis%20Pishdadian"> Adonis Pishdadian</a>, <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20Zahedi"> Ehsan Zahedi</a>, <a href="https://publications.waset.org/abstracts/search?q=Vahideh%20Rashedi"> Vahideh Rashedi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mozhgan%20Mohammadi"> Mozhgan Mohammadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The presence of antibiotics in milk is one of the problems of dairy production units, especially yogurt and cheese, which leads to a decrease in lactic coagulation. Here, to assess the incubation conditions for the fermentation of milk containing antibiotics, concentrations of 50, 75, 100, and 200 ppb of tetracycline were added to each liter of milk. Inoculation process with starter culture performed at three temperatures of 35°C, 45°C, and 50°C. Afterward, pH, acidity, oxidation-reduction potential, and lactic coagulation of yogurt were evaluated. The results showed the existence of antibiotics in milk affects the quality and physicochemical properties of yogurt. However, antibiotic concentration and change in incubation temperature play a crucial role in the lactic coagulation of yogurt, such that the best lactic coagulation was observed at 50°C and a concentration of 50ppb. Hence, for tetracycline concentrations less than 75ppb, a process temperature of 50°C and incubation time of ~10 h recommend for fermentation of milk containing antibiotics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antibiotics%20residues" title="antibiotics residues">antibiotics residues</a>, <a href="https://publications.waset.org/abstracts/search?q=yogurt" title=" yogurt"> yogurt</a>, <a href="https://publications.waset.org/abstracts/search?q=fermentation%20parameters" title=" fermentation parameters"> fermentation parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=incubation%20temperature" title=" incubation temperature"> incubation temperature</a> </p> <a href="https://publications.waset.org/abstracts/151965/optimal-temperature-and-time-for-lactic-coagulation-of-milk-containing-antibiotic-evaluation-of-yogurt-fermentation-parameters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151965.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">99</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">478</span> Determination of Klebsiella Pneumoniae Susceptibility to Antibiotics Using Infrared Spectroscopy and Machine Learning Algorithms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manal%20Suleiman">Manal Suleiman</a>, <a href="https://publications.waset.org/abstracts/search?q=George%20Abu-Aqil"> George Abu-Aqil</a>, <a href="https://publications.waset.org/abstracts/search?q=Uraib%20Sharaha"> Uraib Sharaha</a>, <a href="https://publications.waset.org/abstracts/search?q=Klaris%20Riesenberg"> Klaris Riesenberg</a>, <a href="https://publications.waset.org/abstracts/search?q=Itshak%20Lapidot"> Itshak Lapidot</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Salman"> Ahmad Salman</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20Huleihel"> Mahmoud Huleihel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Klebsiella pneumoniae is one of the most aggressive multidrug-resistant bacteria associated with human infections resulting in high mortality and morbidity. Thus, for an effective treatment, it is important to diagnose both the species of infecting bacteria and their susceptibility to antibiotics. Current used methods for diagnosing the bacterial susceptibility to antibiotics are time-consuming (about 24h following the first culture). Thus, there is a clear need for rapid methods to determine the bacterial susceptibility to antibiotics. Infrared spectroscopy is a well-known method that is known as sensitive and simple which is able to detect minor biomolecular changes in biological samples associated with developing abnormalities. The main goal of this study is to evaluate the potential of infrared spectroscopy in tandem with Random Forest and XGBoost machine learning algorithms to diagnose the susceptibility of Klebsiella pneumoniae to antibiotics within approximately 20 minutes following the first culture. In this study, 1190 Klebsiella pneumoniae isolates were obtained from different patients with urinary tract infections. The isolates were measured by the infrared spectrometer, and the spectra were analyzed by machine learning algorithms Random Forest and XGBoost to determine their susceptibility regarding nine specific antibiotics. Our results confirm that it was possible to classify the isolates into sensitive and resistant to specific antibiotics with a success rate range of 80%-85% for the different tested antibiotics. These results prove the promising potential of infrared spectroscopy as a powerful diagnostic method for determining the Klebsiella pneumoniae susceptibility to antibiotics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=urinary%20tract%20infection%20%28UTI%29" title="urinary tract infection (UTI)">urinary tract infection (UTI)</a>, <a href="https://publications.waset.org/abstracts/search?q=Klebsiella%20pneumoniae" title=" Klebsiella pneumoniae"> Klebsiella pneumoniae</a>, <a href="https://publications.waset.org/abstracts/search?q=bacterial%20susceptibility" title=" bacterial susceptibility"> bacterial susceptibility</a>, <a href="https://publications.waset.org/abstracts/search?q=infrared%20spectroscopy" title=" infrared spectroscopy"> infrared spectroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a> </p> <a href="https://publications.waset.org/abstracts/145001/determination-of-klebsiella-pneumoniae-susceptibility-to-antibiotics-using-infrared-spectroscopy-and-machine-learning-algorithms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145001.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">168</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">477</span> Assessment of Knowledge, Attitude and Perception of Drug Resistance in Rural Communities of ADA District, Central Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Argaw%20Amare">Argaw Amare</a>, <a href="https://publications.waset.org/abstracts/search?q=Abbuna%20Fuffa"> Abbuna Fuffa</a>, <a href="https://publications.waset.org/abstracts/search?q=Stringer%20Andy"> Stringer Andy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Improving public knowledge and changing their attitudes towards antibiotic use will be a crucial early strategy to contain Antibiotic resistance. The current study was undertaken from November 2015 to June 2016. A cross-sectional survey using a pretested questionnaire was conducted on 392 residents (330 male and 62 female) aged 18 and above. Participants were selected randomly. Data was analyzed using simple descriptive statistics; the Chi-square test was used to determine any significant difference. The majority of participants (81%) were farmers in their occupation. Most of the respondents (76%) were not able to define the difference between antimicrobials and antibiotics. Furthermore, (61%) of participants were not able to define what antibiotics and for what purpose they are used. Thirty-four percent of participants do not know the names of antibiotics they have used for their animals and for themselves. Nearly 68% have no knowledge about the disease they have been treated for. The majority of participants (73.5%) agree to complete their course of treatment even if they feel better. About 72.5% of participants disagree that antibiotics are safe and can be used to treat different diseases, without prescription. Most of the participants (95%) treat their animals after diagnosis; more than 80% of them agree to not purchase veterinary drugs from local traders. This study showed that the participants have poor knowledge and good attitude, with an average score of 41.3±16.1% and 79.6±16, respectively. Knowledge and attitude are significantly correlated (p<0.01). The participants in this study had a good attitude toward the rational use of antibiotics. Whereas they lack knowledge with regard to the kinds of antibiotics and the diseases they are prescribed for. Therefore, further educational interventions are necessary to improve their understanding of the antibiotics currently available and the major bacterial diseases they are prescribed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AMR" title="AMR">AMR</a>, <a href="https://publications.waset.org/abstracts/search?q=knoweledge" title=" knoweledge"> knoweledge</a>, <a href="https://publications.waset.org/abstracts/search?q=attitude" title=" attitude"> attitude</a>, <a href="https://publications.waset.org/abstracts/search?q=perception" title=" perception"> perception</a> </p> <a href="https://publications.waset.org/abstracts/178031/assessment-of-knowledge-attitude-and-perception-of-drug-resistance-in-rural-communities-of-ada-district-central-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/178031.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">66</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">476</span> Antibiotic Treatment of Apical Periodontitis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ilma%20Robo">Ilma Robo</a>, <a href="https://publications.waset.org/abstracts/search?q=Saimir%20Heta"> Saimir Heta</a>, <a href="https://publications.waset.org/abstracts/search?q=Gerhard%20Nokaj"> Gerhard Nokaj</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: The method of treatment and the treatment protocols of apical periodontitis are now known, but the ongoing debate remains on whether or not prescription antibiotics should be given to patients suffering from this type of pathology. In fact, as an indication for prescribing antibiotics, this type of pathology remains between clinical indication and contraindication. Material and Methods: This article is of the short-communication type and has the sole purpose of analyzing the clinical picture of apical periodontitis and the fact that the appearance and extent of this pathology in the periapex area passes the stage when the host or the immune cells of the organism of the affected individual, react against bacterial factors. Results: Determining whether or not to prescribe systemic antibiotics according to literature sources can be avoided. In some cases, research in this field about this pathology even indicates endodontic rinsers or irrigants, such as chlorhexidine, in typical cases, mainly in persistent apical periodontitis. Conclusions: In times when bacterial resistance is a hot topic in some fields of scientific research, it is important to divide dental pathologies of bacterial origin into those when systemic antibiotic prescriptions must be given and those when every clinical issue is resolved only with endodontic root canal treatment. Even certain sources of published literature show the specifics of the most effective antibiotics against the bacterial flora causing the pathology of apical periodontitis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=endodontic%20treatment" title="endodontic treatment">endodontic treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=apical%20periodontitis" title=" apical periodontitis"> apical periodontitis</a>, <a href="https://publications.waset.org/abstracts/search?q=antibiotics" title=" antibiotics"> antibiotics</a>, <a href="https://publications.waset.org/abstracts/search?q=chlorhexidine" title=" chlorhexidine"> chlorhexidine</a> </p> <a href="https://publications.waset.org/abstracts/182705/antibiotic-treatment-of-apical-periodontitis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182705.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">69</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">475</span> Antibiotic and Fungicide Exposure Reveal the Evolution of Soil-Lettuce System Resistome</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chenyu%20Huang">Chenyu Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Minrong%20Cui"> Minrong Cui</a>, <a href="https://publications.waset.org/abstracts/search?q=Hua%20Fang"> Hua Fang</a>, <a href="https://publications.waset.org/abstracts/search?q=Luqing%20Zhang"> Luqing Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yunlong%20Yu"> Yunlong Yu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The emergence and spread of antibiotic resistance genes (ARGs) have become a pressing issue in global agricultural production. However, understanding how these ARGs spread across different spatial scales, especially when exposed to both pesticides and antibiotics, has remained a challenge. Here, metagenomic assembly and binning methodologies were used to determine the mechanism of ARG propagation within soil-lettuce systems exposed to both fungicides and antibiotics. The results of our study showed that the presence of fungicide and antibiotic stresses had a significant impact on certain bacterial communities. Notably, we observed that ARGs were primarily transferred from the soil to the plant through plasmids. The selective pressure exerted by fungicides and antibiotics contributed to an increase in unique ARGs present on lettuce leaves. Moreover, ARGs located on chromosomes and plasmids followed different transmission patterns. The presence of diverse selective pressures, a result of compound treatments involving antibiotics and fungicides, amplifies this phenomenon. Consequently, there is a higher probability of bacteria developing multi-antibiotic resistance under the combined pressure of fungicides and antibiotics. In summary, our findings highlight that combined fungicide and antibiotic treatments are more likely to drive the acquisition of ARGs within the soil-plant system and may increase the risk of human ingestion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=soil-lettuce%20system" title="soil-lettuce system">soil-lettuce system</a>, <a href="https://publications.waset.org/abstracts/search?q=fungicide" title=" fungicide"> fungicide</a>, <a href="https://publications.waset.org/abstracts/search?q=antibiotic" title=" antibiotic"> antibiotic</a>, <a href="https://publications.waset.org/abstracts/search?q=ARG" title=" ARG"> ARG</a>, <a href="https://publications.waset.org/abstracts/search?q=transmission" title=" transmission"> transmission</a> </p> <a href="https://publications.waset.org/abstracts/176413/antibiotic-and-fungicide-exposure-reveal-the-evolution-of-soil-lettuce-system-resistome" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176413.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">106</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">474</span> Infrared Spectroscopy in Tandem with Machine Learning for Simultaneous Rapid Identification of Bacteria Isolated Directly from Patients' Urine Samples and Determination of Their Susceptibility to Antibiotics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20Huleihel">Mahmoud Huleihel</a>, <a href="https://publications.waset.org/abstracts/search?q=George%20Abu-Aqil"> George Abu-Aqil</a>, <a href="https://publications.waset.org/abstracts/search?q=Manal%20Suleiman"> Manal Suleiman</a>, <a href="https://publications.waset.org/abstracts/search?q=Klaris%20Riesenberg"> Klaris Riesenberg</a>, <a href="https://publications.waset.org/abstracts/search?q=Itshak%20Lapidot"> Itshak Lapidot</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Salman"> Ahmad Salman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Urinary tract infections (UTIs) are considered to be the most common bacterial infections worldwide, which are caused mainly by Escherichia (E.) coli (about 80%). Klebsiella pneumoniae (about 10%) and Pseudomonas aeruginosa (about 6%). Although antibiotics are considered as the most effective treatment for bacterial infectious diseases, unfortunately, most of the bacteria already have developed resistance to the majority of the commonly available antibiotics. Therefore, it is crucial to identify the infecting bacteria and to determine its susceptibility to antibiotics for prescribing effective treatment. Classical methods are time consuming, require ~48 hours for determining bacterial susceptibility. Thus, it is highly urgent to develop a new method that can significantly reduce the time required for determining both infecting bacterium at the species level and diagnose its susceptibility to antibiotics. Fourier-Transform Infrared (FTIR) spectroscopy is well known as a sensitive and rapid method, which can detect minor molecular changes in bacterial genome associated with the development of resistance to antibiotics. The main goal of this study is to examine the potential of FTIR spectroscopy, in tandem with machine learning algorithms, to identify the infected bacteria at the species level and to determine E. coli susceptibility to different antibiotics directly from patients' urine in about 30minutes. For this goal, 1600 different E. coli isolates were isolated for different patients' urine sample, measured by FTIR, and analyzed using different machine learning algorithm like Random Forest, XGBoost, and CNN. We achieved 98% success in isolate level identification and 89% accuracy in susceptibility determination. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=urinary%20tract%20infections%20%28UTIs%29" title="urinary tract infections (UTIs)">urinary tract infections (UTIs)</a>, <a href="https://publications.waset.org/abstracts/search?q=E.%20coli" title=" E. coli"> E. coli</a>, <a href="https://publications.waset.org/abstracts/search?q=Klebsiella%20pneumonia" title=" Klebsiella pneumonia"> Klebsiella pneumonia</a>, <a href="https://publications.waset.org/abstracts/search?q=Pseudomonas%20aeruginosa" title=" Pseudomonas aeruginosa"> Pseudomonas aeruginosa</a>, <a href="https://publications.waset.org/abstracts/search?q=bacterial" title=" bacterial"> bacterial</a>, <a href="https://publications.waset.org/abstracts/search?q=susceptibility%20to%20antibiotics" title=" susceptibility to antibiotics"> susceptibility to antibiotics</a>, <a href="https://publications.waset.org/abstracts/search?q=infrared%20microscopy" title=" infrared microscopy"> infrared microscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a> </p> <a href="https://publications.waset.org/abstracts/145194/infrared-spectroscopy-in-tandem-with-machine-learning-for-simultaneous-rapid-identification-of-bacteria-isolated-directly-from-patients-urine-samples-and-determination-of-their-susceptibility-to-antibiotics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145194.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">170</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">473</span> The Role of Biosecurity in Sustainable Aquaculture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Barbara%20Montwill">Barbara Montwill</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The last three decades of continuing increase in the farming of aquatic animals worldwide placed a biosecurity in a different perspective. An introduction of new countries, technologies, species to aquaculture, increased movement of animals are a few factors the might be associated with biosecurity risks. Most farms depend on trade for various inputs such as broodstock, post-larvae/fingerlings and feed. These inputs represent potential pathways by which pathogens can enter farming operations and create conditions for emergence of new or reoccurrence of diseases and production loses. Farm biosecurity should be considered an essential component of a national aquatic animal biosecurity program and together with adequate import and export controls can lead to the development of successful aquaculture industry as a reliable source of safe seafood product.

It appears that many antibiotics, when used at low concentrations, have in common the ability to activate or repress gene transcription, which is distinct from their inhibitory effect. There have been comparatively few studies on the potential of antibiotics as a specific chemical signal that can trigger a variety of biological functions. Therefore, this study was carried out to determine the effect of Streptomycin Sulfate in regulating extracellular proteins secreted by Bacillus subtilis ATCC21332. Results of Microdilution assay showed that the Minimum Inhibition Concentration (MIC) of Streptomycin Sulfate on B. subtilis ATCC21332 was 2.5 mg/ml. The bacteria cells were then exposed to Streptomycin Sulfate at concentration of 0.01 MIC before being further incubated for 48h to 72 h. The extracellular proteins secreted were then isolated and analyzed by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). Proteins profile revealed that three additional bands with approximate sizes of 30 kDa, 22 kDa and 23 kDa were appeared for the treated bacteria with Streptomycin Sulfate. Thus, B. subtilis ATCC21332 in stressful condition with the presence of Streptomycin Sulfate at low concentration could induce the extracellular proteins secretion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bacillus%20subtilis%20ATCC21332" title="Bacillus subtilis ATCC21332">Bacillus subtilis ATCC21332</a>, <a href="https://publications.waset.org/abstracts/search?q=streptomycin%20sulfate" title=" streptomycin sulfate"> streptomycin sulfate</a>, <a href="https://publications.waset.org/abstracts/search?q=extracellular%20proteins" title=" extracellular proteins"> extracellular proteins</a>, <a href="https://publications.waset.org/abstracts/search?q=antibiotics" title=" antibiotics"> antibiotics</a> </p> <a href="https://publications.waset.org/abstracts/11187/extracellular-protein-secreted-by-bacillus-subtilis-atcc21332-in-the-presence-of-streptomycin-sulfate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11187.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">284</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">471</span> Oral Antibiotics in Trans-Rectal Prostate Biopsy and Its Efficacy to Reduce Infectious Complications: Systematic Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohand%20Yaghi">Mohand Yaghi</a>, <a href="https://publications.waset.org/abstracts/search?q=O.%20Kehinde"> O. Kehinde</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: For the diagnosis of prostate cancer Trans-rectal prostate biopsy (TRPB) is used commonly, the procedure is associated with infective complications. There is evidence that antibiotics (ABx) decrease infective events after TRPB, but different regimens are used. Aim: To systematically review different regimens of prophylactic oral antibiotics in TRPB. Design: Medline, Embase, Clinical trials site, and Cochrane library were searched, experts were consulted about relevant studies. Randomized clinical trials (RCT) conducted in the last twenty years, which investigated different oral antibiotic regimens in TRPB, and compared their efficacy to reduce infectious complications were analyzed. Measurements: Primary outcomes were bacteriuria, urinary tract infection (UTI), fever, bacteremia, sepsis. Secondary outcomes were hospitalization rate, and the prevalence of ABx-resistant bacteria. Results: Nine trials were eligible with 3012 patients. Antibiotics prevented bacteriuria (3.5% vs. 9.88%), UTI (4.46% vs. 9.75%), and hospitalization (0.21% vs. 2.13%) significantly in comparison with placebo or no treatment. No significant difference was found in all outcomes of the review between the single dose regimen and the 3 days. The single dose regimen was as effective as the multiple dose except in Bacteriuria (6.75% vs. 3.25%), and the prevalence of ABx-resistant bacteria (1.57% vs. 0.27%). Quinolones reduced only UTI significantly in comparison with other antibiotics. Lastly, Ciprofloxacin is the best Quinolone to prevent UTI, and hospitalization. Conclusion: it is essential to prescribe prophylactic Antibiotics in TRPB. No conclusive evidence could be claimed about the superiority of the multiple or the 3 days regimens to the single dose regimen. Unexpectedly, ABx-resistant bacteria was identified more often in the single dose cohorts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=infection" title="infection">infection</a>, <a href="https://publications.waset.org/abstracts/search?q=prostate%20cancer" title=" prostate cancer"> prostate cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=sepsis" title=" sepsis"> sepsis</a>, <a href="https://publications.waset.org/abstracts/search?q=TRPB" title=" TRPB"> TRPB</a> </p> <a href="https://publications.waset.org/abstracts/34146/oral-antibiotics-in-trans-rectal-prostate-biopsy-and-its-efficacy-to-reduce-infectious-complications-systematic-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34146.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">368</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">470</span> Achieving Appropriate Use of Antibiotics through Pharmacists’ Intervention at Practice Point: An Indian Study Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Parimalakrishnan%20Sundararjan">Parimalakrishnan Sundararjan</a>, <a href="https://publications.waset.org/abstracts/search?q=Madheswaran%20Murugan"> Madheswaran Murugan</a>, <a href="https://publications.waset.org/abstracts/search?q=Dhanya%20Dharman"> Dhanya Dharman</a>, <a href="https://publications.waset.org/abstracts/search?q=Yatindra%20Kumar"> Yatindra Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sudhir%20Singh%20Gangwar"> Sudhir Singh Gangwar</a>, <a href="https://publications.waset.org/abstracts/search?q=Guru%20Prasad%20Mohanta"> Guru Prasad Mohanta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Antibiotic resistance AR is a global issue, India started to redress the issues of antibiotic resistance late and it plans to have: active surveillance of microbial resistance and promote appropriate use of antibiotics. The present study attempted to achieve appropriate use of antibiotics through pharmacists’ intervention at practice point. In a quasi-experimental prospective cohort study, the cases with bacteremia from four hospitals were identified during 2015 and 2016 for intervention. The pharmacists centered intervention: active screening of each prescription and comparing with the selection of antibiotics with susceptibility of the bacteria. Wherever irrationality noticed, it was brought to the notice of the treating physician for making changes. There were two groups: intervention group and control group without intervention. The active screening and intervention in 915 patients has reduced therapeutic regimen time in patients with bacteremia. The intervention group showed the decreased duration of hospital stay 3.4 days from 5.1 days. Further, multivariate modeling of patients who were in control group showed that patients in the intervention group had a significant decrease in both duration of hospital stay and infection-related mortality. Unlike developed countries, pharmacists are not active partners in patient care in India. This unique attempt of pharmacist’ invention was planned in consultation with hospital authorities which proved beneficial in terms of reducing the duration of treatment, hospital stay, and infection-related mortality. This establishes the need for a collaborative decision making among the health workforce in patient care at least for promoting rational use of antibiotics, an attempt to combat resistance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antibiotics%20resistance" title="antibiotics resistance">antibiotics resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=intervention" title=" intervention"> intervention</a>, <a href="https://publications.waset.org/abstracts/search?q=bacteremia" title=" bacteremia"> bacteremia</a>, <a href="https://publications.waset.org/abstracts/search?q=multivariate%20modeling" title=" multivariate modeling "> multivariate modeling </a> </p> <a href="https://publications.waset.org/abstracts/85711/achieving-appropriate-use-of-antibiotics-through-pharmacists-intervention-at-practice-point-an-indian-study-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85711.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">182</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">469</span> Prevalence and Antibiotic Resistance Patterns of Salmonella from Retail Dressed Chickens (Gallus gallus domesticus) in Wet Markets of Cavite, Philippines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chester%20Joshua%20V.%20Saldana">Chester Joshua V.

The overall prevalence of Salmonella in five wet markets in Cavite was 13.33 percent. Samples from Bacoor yielded the highest prevalence rate of 26.6 percent, followed by Imus (23.3%), Dasmarinas (11.6%), Trece Martires (3.3%) and Tagaytay (1.6%). Seven serotypes (serogroups B, C2, C3, D1 and E1) were isolated which include Salmonella weltevreden, S. derby, S. newport, S. albany, S. typhimurium, and S. enteritidis. Salmonella weltevreden was the predominant serotype while S. typhi and S. albany were the least common. Among the 15 antibiotics tested, resistance to ampicillin, tetracycline, and cephalexin was exhibited by all the isolates while 5 percent showed resistance to gentamicin, 2.5 percent to streptomycin and 12.5 percent to nitrofurantoin. One isolate was resistant to four antibiotics whereas most isolates of S. enteritidis were resistant to 2 to 5 antibiotics. Four resistance patterns were recorded.

The aim of this prospective audit was to identify any problems with antimicrobial prescribing including documentation of the relevant aspects as well as appropriateness of antibiotics use. The audit was conducted on the surgical wards in a teaching hospital in the UK. Methods: Standards included the indication, duration, choice, and prescription of antibiotic should be in line with current Regional Guidelines and should be clearly documented on the prescription chart. There should be an entry in each patients’ medical record of the diagnosis and indication for each acute antibiotic prescription issued. All prescriptions should clearly document the route, frequency and dose of antibiotic. Data collection was done for 2 weeks in the month of March 2014. A proforma including all the questions above was completed for all the patients. The results were analysed using Excel. Results: 35 patients in total were selected for the audit. 85.7% of patients had indication of antibiotic documented on the prescription chart and 68.5% of patients had indication documented in the notes. The antibiotic used was in line with hospital guidelines in 45.7% of patients, however, in a further 28.5% of patients the reason for the antibiotic prescription was microbiology approved. Therefore, in total 74.2% of patients had been prescribed appropriate antibiotics. The duration of antibiotic was documented in 68.6% of patients and the antibiotic was reviewed in 37.1% of patients. The dose, frequency and route was documented clearly in 100% of patients. Conclusion: Overall, prescribing can be improved on the surgical wards in this hospital. Only 37.1% of patients had clear documentation of a review of antibiotics. It may be that antibiotics have been reviewed but this should be clearly highlighted on the prescription chart or the notes. Failure to review antibiotics can lead to poor patient care and antimicrobial resistance and therefore it is important to address this. It is also important to address the appropriateness of antibiotics as inappropriate antibiotic prescription can lead to failure of treatment as well as antimicrobial resistance. The good points from the audit was that all patients had clear documentation of dose, route and frequency which is extremely important in the administration of antibiotics. Recommendations from this audit included to emphasize good antimicrobial prescribing at induction (twice yearly), an antimicrobial handbook for junior doctors, and re-audit in 6 months time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=prescribing" title="prescribing">prescribing</a>, <a href="https://publications.waset.org/abstracts/search?q=antimicrobial" title=" antimicrobial"> antimicrobial</a>, <a href="https://publications.waset.org/abstracts/search?q=indication" title=" indication"> indication</a>, <a href="https://publications.waset.org/abstracts/search?q=duration" title=" duration"> duration</a> </p> <a href="https://publications.waset.org/abstracts/11047/a-prospective-audit-to-look-into-antimicrobial-prescribing-in-the-clinical-setting-in-a-teaching-hospital-in-the-uk" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11047.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">303</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">466</span> Antimicrobial Resistance: Knowledge towards Antibiotics in a Mexican Population</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=L.%20D.%20Upegui">L.

There have been identified risk factors that are related to the misuse and overuse of antibiotics, like socio-demographic characteristics and psychological aspects of the individuals that have not been explored objectively due to a lack of valid and reliable instruments for their measurement. Objective: To validate a questionnaire for the evaluation of the levels of knowledge related to the use of antibiotics in a Mexican population. Materials and Methods: Analytical cross-sectional observational study. The questionnaire consists of 12 items to evaluated knowledge (1=no, 2=not sure, 3=yes) regarding the use of antibiotics, with higher scores corresponding to a higher level of knowledge. Data are collected in a sample of students. Data collection is still ongoing. In this abstract preliminary results of 30 respondents are reported which were collected during pilot-testing. The validation of the instrument was done using the Rasch model. Fit to the Rasch model was tested checking overall fit to the model, unidimensionality, local independence and evaluating the presence of Differential Item Functioning (DIF) by age and gender. The software Rumm2030 and the SPSS were used for the analyses. Results: The participants of the pilot-testing presented an average age of 32 years ± 12.6 and 53% were women. The preliminary results indicated that the items showed good fit to the Rasch model (chi-squared=12.8 p=0.3795). Unidimensionality (number of significant t-tests of 3%) could be proven, the items were locally independent, and no DIF was observed. Knowledge was the smallest regarding statements on the role of antibiotics in treating infections, e.g., most of the respondents did not know that antibiotics would not work against viral infections (70%) and that they could also cause side effects (87%). The knowledge score ranged from 0 to 100 points with a transformed measurement (mean of knowledge 27.1 ± 4.8). Conclusions: The instrument showed good psychometric proprieties. The low scores of knowledge about antibiotics suggest that misinterpretations on the use of these medicaments were prevalent, which could influence the production of antibiotic resistance. The application of this questionnaire will allow the objective identification of 'Hight risk groups', which will be the target population for future educational campaigns, to reduce the knowledge gaps on the general population as an effort against antibiotic resistance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antibiotics" title="antibiotics">antibiotics</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge" title=" knowledge"> knowledge</a>, <a href="https://publications.waset.org/abstracts/search?q=misuse" title=" misuse"> misuse</a>, <a href="https://publications.waset.org/abstracts/search?q=overuse" title=" overuse"> overuse</a>, <a href="https://publications.waset.org/abstracts/search?q=questionnaire" title=" questionnaire"> questionnaire</a>, <a href="https://publications.waset.org/abstracts/search?q=Rasch%20model" title=" Rasch model"> Rasch model</a>, <a href="https://publications.waset.org/abstracts/search?q=validation" title=" validation"> validation</a> </p> <a href="https://publications.waset.org/abstracts/80096/antimicrobial-resistance-knowledge-towards-antibiotics-in-a-mexican-population" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80096.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">156</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">465</span> Occurrence of Antibiotics of Veterinary Use in Water of the Lake Titicaca: Its Environmental Implication and Human Health</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Franz%20Zirena%20Vilca">Franz Zirena Vilca</a>, <a href="https://publications.waset.org/abstracts/search?q=Nestor%20Cahui%20Galarza"> Nestor Cahui Galarza</a>, <a href="https://publications.waset.org/abstracts/search?q=Walter%20Alejandro%20Zamalloa%20Cuba"> Walter Alejandro Zamalloa Cuba</a>, <a href="https://publications.waset.org/abstracts/search?q=Edith%20Tello%20Palma"> Edith Tello Palma</a>, <a href="https://publications.waset.org/abstracts/search?q=Teofilo%20Donaires%20Flores"> Teofilo Donaires Flores</a>, <a href="https://publications.waset.org/abstracts/search?q=Valdemar%20Luiz%20Tornisielo"> Valdemar Luiz Tornisielo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The production of rainbow trout in the Lake Titicaca represents an important economic activity for Peru. The city of Puno is responsible for 83% of this production, so the use of antibiotics within the aquaculture system is not alien to this reality. Meanwhile, the waters of Lake Titicaca represent an important source for the supply of drinking water for 80% of the population of the Puno city. In this paper, twelve antibiotics for veterinary use were monitored in water samples during two seasons: dry (July 2015) and rainy (February 2016), water samples from trout production systems, near the water catching point in the lake and drinking water in the city house of Puno were considered. The samples were analyzed using liquid chromatography coupled to mass spectrometry and solid online phase extraction (On-line SPE-LC-MS/MS), all samples analyzed showed concentrations of Ciprofloxacin up to 65.2 ng L⁻¹ at the rainy season. On the other hand, 63% of water samples from the dry season and 36 % from the rainy season showed Chlortetracycline up to 8.7 and 6.1 ng L⁻¹, respectively. The presence of residues of veterinary antibiotics in drinking water means a serious health risk for 80% of the population of Puno since all these people are supplied from this source. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chromatography" title="chromatography">chromatography</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA%20damage" title=" DNA damage"> DNA damage</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20risk" title=" environmental risk"> environmental risk</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20pollution" title=" water pollution"> water pollution</a> </p> <a href="https://publications.waset.org/abstracts/94507/occurrence-of-antibiotics-of-veterinary-use-in-water-of-the-lake-titicaca-its-environmental-implication-and-human-health" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94507.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">230</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">464</span> Synthesis, Antibacterial Activities, and Synergistic Effects of Novel Juglone and Naphthazarin Derivatives Against Clinical Methicillin-Resistant Staphylococcus aureus Strains</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zohra%20Benfodda">Zohra Benfodda</a>, <a href="https://publications.waset.org/abstracts/search?q=Valentin%20Duvauchelle"> Valentin Duvauchelle</a>, <a href="https://publications.waset.org/abstracts/search?q=Chaimae%20Majdi"> Chaimae Majdi</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20B%C3%A9nim%C3%A9lis"> David Bénimélis</a>, <a href="https://publications.waset.org/abstracts/search?q=Catherine%20Dunyach-Remy"> Catherine Dunyach-Remy</a>, <a href="https://publications.waset.org/abstracts/search?q=Patrick%20Meffre"> Patrick Meffre</a> </p> <p class="card-text"><strong>Abstract:</strong></p> New antibiotics are necessary to treat microbial pathogens, especially ESKAPE pathogens that are becoming increasingly resistant to available treatment. Despite the medical need, the number of newly approved drugs continues to decline. The majority of antibiotics under clinical development are natural products or derivatives thereof. 43 juglone/naphthazarin derivatives were synthesized using Minisci-type direct C–H alkylation and evaluated for their antibacterial properties against various clinical and reference Gram-positive MSSA, clinical Gram-positive MRSA. Different compounds of the synthesized series showed promising activity against clinical and reference MSSA (MIC: 1–8 μg/ml) and good efficacy against clinical MRSA (MIC: 2–8 μg/ml) strains. The synergistic effects of active compounds were evaluated with reference antibiotics (vancomycin and cloxacillin), and it was found that the antibiotic combination with those active compounds efficiently enhanced the antimicrobial activity and consequently the MIC values of reference antibiotics were lowered up to 1/16th of the original MIC. These synthesized compounds did not present hemolytic activity on sheep red blood cells. In addition to the in silico prediction of ADME profile parameter which is promising and encouraging for further development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=juglone" title="juglone">juglone</a>, <a href="https://publications.waset.org/abstracts/search?q=naphthazarin" title=" naphthazarin"> naphthazarin</a>, <a href="https://publications.waset.org/abstracts/search?q=antibacterial" title=" antibacterial"> antibacterial</a>, <a href="https://publications.waset.org/abstracts/search?q=clinical%20MRSA" title=" clinical MRSA"> clinical MRSA</a>, <a href="https://publications.waset.org/abstracts/search?q=synergistic%20studies" title=" synergistic studies"> synergistic studies</a>, <a href="https://publications.waset.org/abstracts/search?q=MIC%20determination" title=" MIC determination"> MIC determination</a> </p> <a href="https://publications.waset.org/abstracts/149176/synthesis-antibacterial-activities-and-synergistic-effects-of-novel-juglone-and-naphthazarin-derivatives-against-clinical-methicillin-resistant-staphylococcus-aureus-strains" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149176.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">126</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">463</span> Effect Mechanisms of Aromatic Plants: Effects on Intestinal Health and Broiler Feeding</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ozlem%20Durna%20Aydin">Ozlem Durna Aydin</a>, <a href="https://publications.waset.org/abstracts/search?q=Gultekin%20Yildiz"> Gultekin Yildiz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Antibiotics are microbial metabolites with low molecular weight produced by fungi and algae, inhibiting the development of other microorganisms even in low growth. Antibiotics have been used as growth factors in animal feeds for many years. They prohibited; because of increased residue problem and increased resistance to antibiotics in bacteria due to prolonged use. Aromatic plants and extracts have attracted the attention of scientists nowadays due to positive reasons such as confidence of the community to the products those are coming from nature, desire to consume, and no residue problems. Plant extracts are obtained from aromatic plants, and they come forward with antifungal, antibacterial, antiviral, antioxidant and antilipidemic properties. It has been stated that intestinal histomorphology and microbiosis are positively affected by the use of plant extract in feeds. In the present day, aromatic plants and extracts are a remarkable research field with intriguing unknowns in the field of animal nutrition, and they continue to exist in the journal in vitro and in vivo studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aromatic%20plant" title="aromatic plant">aromatic plant</a>, <a href="https://publications.waset.org/abstracts/search?q=broilers" title=" broilers"> broilers</a>, <a href="https://publications.waset.org/abstracts/search?q=extract%20mechanism%20of%20action" title=" extract mechanism of action"> extract mechanism of action</a>, <a href="https://publications.waset.org/abstracts/search?q=intestinal%20health" title=" intestinal health"> intestinal health</a> </p> <a href="https://publications.waset.org/abstracts/85014/effect-mechanisms-of-aromatic-plants-effects-on-intestinal-health-and-broiler-feeding" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85014.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">166</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">462</span> Associations and Interactions of Delivery Mode and Antibiotic Exposure with Infant Cortisol Level: A Correlational Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samarpreet%20Singh">Samarpreet Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Gerald%20Giesbrecht"> Gerald Giesbrecht</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Both c-section and antibiotic exposure are linked to gut microbiota imbalance in infants. Such disturbance is associated with the Hypothalamic-Pituitary-Adrenal (HPA) axis function. However, the literature only has contradicting evidence for the association between c-sections and the HPA axis. Therefore, this study aims to test if the mode of delivery and antibiotics exposure is associated with the HPA axis. Also, whether exposure to both interacts with the HPA-axis. It was hypothesized that associations and interactions would be observed. Secondary data analysis was used for this co-relational study. Data for the mode of delivery and antibiotics exposure variables were documented from hospital records or self-questionnaires. In addition, cortisol levels (Area under the curve with respect to increasing (AUCi) and Area under the curve with respect to ground (AUCg)) were based on saliva collected from three months old during the infant’s visit to the lab and after drawing blood. One-way and between-subject ANOVA analyses were run on data. No significant association between delivery mode and infant cortisol level was found, AUCi and AUCg, p > .05. Only the infant’s AUCg was found to be significantly higher if there were antibiotics exposure at delivery (p = .001) or their mothers were exposed during pregnancy (p < .05). Infants born by c-section and exposed to antibiotics at three months had higher AUCi than those born vaginally, p < .02. These results imply that antibiotic exposure before three months is associated with an infant’s stress response. The association might increase if antibiotic exposure occurs three months after a c-section birth. However, more robust and causal evidence in future studies is needed, given a variable group’s statistically weak sample size. Nevertheless, the results of this study still highlight the unintended consequences of antibiotic exposure during delivery and pregnancy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=HPA-axis" title="HPA-axis">HPA-axis</a>, <a href="https://publications.waset.org/abstracts/search?q=antibiotics" title=" antibiotics"> antibiotics</a>, <a href="https://publications.waset.org/abstracts/search?q=c-section" title=" c-section"> c-section</a>, <a href="https://publications.waset.org/abstracts/search?q=gut-microbiota" title=" gut-microbiota"> gut-microbiota</a>, <a href="https://publications.waset.org/abstracts/search?q=development" title=" development"> development</a>, <a href="https://publications.waset.org/abstracts/search?q=stress" title=" stress"> stress</a> </p> <a href="https://publications.waset.org/abstracts/168087/associations-and-interactions-of-delivery-mode-and-antibiotic-exposure-with-infant-cortisol-level-a-correlational-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168087.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">72</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">461</span> Determination of Multidrug-Resistant Livestock Associated Bacteria from Goats, Cows, and Buffaloes in Pokhara Kaski</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ganga%20Sagar%20Bhattarai">Ganga Sagar Bhattarai</a>, <a href="https://publications.waset.org/abstracts/search?q=Swastika%20Gurung"> Swastika Gurung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Antibiotics were being misused in both humans and animals, which led to the development of multidrug-resistant microorganisms. Antibiotic abuse is likely rampant among goats, cows, and buffaloes in order to boost growth and reduce production losses. The aim of this study is to know the multidrug resistance (MDR) bacteria in goats, cows, and buffaloes. Out of 68 samples that were examined, S. aureus, Bacillus spp., E. coli, Shigella spp., Klebsiella spp., S. epidremidis, and Salmonella spp. were isolated. S. aureus was the highest isolated bacteria (91.17%), Bacillus spp. (61.76%), E. coli (48.52%), Shigella spp. (22.05%), Klebsiella spp. (17.64%), S. epidermidis (13.23%), and the Salmonella spp. (7.35%). Salmonella spp. and E. coli showed multidrug resistance to at least four antibiotics, including Amoxicillin, Tetracycline, Piperacillin, and Ciprofloxacin, in Salmonella and to at least three antibiotics, including Amoxicillin, Tetracycline, and Nalidic acid. The highest resistance bacteria Salmonella spp. showed (57.14%) E. coli and Bacillus spp. showed (42.85%) S. aureus, S. epidermidis, and Shigella spp. showed (28.57%), and Klebsiella spp. showed (14.28%). This study showed that antibiotic-resistant bacteria with high levels of Amoxicillin, Penicillin, and Tetracycline resistance are present in healthy farm animals such as goats, cows, and buffaloes. Options for antibiotic therapy in both humans and animals will likely be limited as a result. The use, distribution, storage, and sale of antibiotics in veterinary practices must consequently be under strict control. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multidrug%20resistance" title="multidrug resistance">multidrug resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=multidrug%20resistance%20bacteria" title=" multidrug resistance bacteria"> multidrug resistance bacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=susceptibility%20testing" title=" susceptibility testing"> susceptibility testing</a>, <a href="https://publications.waset.org/abstracts/search?q=bacterial%20infections" title=" bacterial infections"> bacterial infections</a> </p> <a href="https://publications.waset.org/abstracts/169059/determination-of-multidrug-resistant-livestock-associated-bacteria-from-goats-cows-and-buffaloes-in-pokhara-kaski" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169059.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">106</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">460</span> Bacteriological Culture Methods and its Uses in Clinical Pathology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Prachi%20Choudhary">Prachi Choudhary</a>, <a href="https://publications.waset.org/abstracts/search?q=Jai%20Gopal%20Sharma"> Jai Gopal Sharma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Microbial cultures determine the type of organism, its abundance in the tested sample, or both. It is one of the primary diagnostic methods of microbiology. It is used to determine the cause of infectious disease by letting the agent multiply in a predetermined medium. Different bacteria produce colonies that may be very distinct from the bacterial species that produced them. To culture any pathogen or microorganism, we should first know about the types of media used in microbiology for culturing. Sometimes sub culturing is also done in various microorganisms if some mixed growth is seen in culture. Nearly 3 types of culture media based on consistency – solid, semi-solid, and liquid (broth) media; are further explained in the report. Then, The Five I's approach is a method for locating, growing, observing, and characterizing microorganisms, including inoculation and incubation. Isolation, inspection, and identification. For identification of bacteria, we have to culture the sample like urine, sputum, blood, etc., on suitable media; there are different methods of culturing the bacteria or microbe like pour plate method, streak plate method, swabbing by needle, pipetting, inoculation by loop, spreading by spreader, etc. After this, we see the bacterial growth after incubation of 24 hours, then according to the growth of bacteria antibiotics susceptibility test is conducted; this is done for sensitive antibiotics or resistance to that bacteria, and also for knowing the name of bacteria. Various methods like the dilution method, disk diffusion method, E test, etc., do antibiotics susceptibility tests. After that, various medicines are provided to the patients according to antibiotic sensitivity and resistance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inoculation" title="inoculation">inoculation</a>, <a href="https://publications.waset.org/abstracts/search?q=incubation" title=" incubation"> incubation</a>, <a href="https://publications.waset.org/abstracts/search?q=isolation" title=" isolation"> isolation</a>, <a href="https://publications.waset.org/abstracts/search?q=antibiotics%20suspectibility%20test" title=" antibiotics suspectibility test"> antibiotics suspectibility test</a>, <a href="https://publications.waset.org/abstracts/search?q=characterizing" title=" characterizing"> characterizing</a> </p> <a href="https://publications.waset.org/abstracts/161272/bacteriological-culture-methods-and-its-uses-in-clinical-pathology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161272.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">82</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">459</span> Physicochemical Profile of Essential Oil of Daucus carota</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nassima%20Behidj-Benyounes">Nassima Behidj-Benyounes</a>, <a href="https://publications.waset.org/abstracts/search?q=Thoraya%20Dahmene"> Thoraya Dahmene</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Essential oils have a significant antimicrobial activity.

Secondary objectives: Prevalence of ESBL E. coli from community urine samples, identify the best empirical oral antibiotics with the least resistance rate for UTI and identify alternative oral antibiotics for testing and utilization. Methods: This study is a retrospective descriptive study of the last three years in five major hospitals in Oman (Khowla Hospital, AN’Nahdha Hospital, Rustaq Hospital, Nizwa Hospital, and Ibri Hospital) equipped with a microbiologist. Inclusion criteria include all eligible outpatient urine culture isolates, excluding isolates from admitted patients with hospital-acquired urinary tract infections. Data was collected through the MOH database. The MOH hospitals are using different types of testing, automated methods like Vitek2 and manual methods. Vitek2 machine uses the principle of the fluorogenic method for organism identification and a turbidimetric method for susceptibility testing. The manual method is done by double disc diffusion for identifying ESBL and the disc diffusion method is for antibiotic susceptibility. All laboratories follow the clinical laboratory science institute (CLSI) guidelines. Analysis was done by SPSS statistical package. Results: Total urine cultures were (23048). E. coli grew in (11637) 49.6% of the urine, whereas (2199) 18.8% of those were confirmed as ESBL. As expected, the resistance rate to amoxicillin and cefuroxime is 100%. Moreover, the susceptibility of those ESBL-producing E. coli to nitrofurantoin, trimethoprim+sulfamethoxazole, ciprofloxacin and amoxicillin-clavulanate is progressing over the years; however, still low. ESBL E. coli was predominating in the female gender and those aged 66-74 years old throughout all the years. Other oral antibiotic options need to be explored and tested so that we add to the pool of oral antibiotics for ESBL E. coli causing UTI in the community. Conclusion: High rate of ESBL E. coli in urine from the community. The high resistance rates to oral antibiotics highlight the need for alternative treatment options for UTIs caused by these bacteria. Further research is needed to identify new and effective treatments for UTIs caused by ESBL-E.

Pseudomonas is a notorious opportunistic pathogen involoved in nosocomial infections and exhibit innate resistance to many antibiotics. The present study was conducted to assess the prevalence, levels of antimicrobial susceptibility and resistance mechanisms of Pseudomonas. A total of thirty clinical strains of Pseudomonas were isolated from different clinical sites of infection. All clinical specimens were collected from Chughtais Lahore Lab. Jail road, during 8-07-2010 to 11-01-2011. Biochemical characterization was done using routine biochemical tests. Antimicrobial susceptibility was determined by Kirby-Baeur method. The plasmids were isolated from all the strains and digested with restriction enzyme PstI and EcoRI. Transfer of Multi-resistance plasmid was checked via transformation and conjugation to confirm the plasmid mediated resistance to antibiotics. The prevalence of Pseudomonas in clinical specimens was found out to be 14% of all bacterial infections. IPM has shown to be the most effective drug against Pseudomonas followed by CES, PTB and meropenem, wheareas most of the Pseudomonas strains have developed significant resistance against Penicillins and some Cephalasporins. Antibiotic resistance determinants were carried by plasmids, as they conferred resistance to transformed K1 strains. The isolates readily undergo conjugation, transferring the resistant genes to other strains, illustrating the high rates of cross infection and nosocomial infection in the immunocompromised patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pseudomonas" title="pseudomonas">pseudomonas</a>, <a href="https://publications.waset.org/abstracts/search?q=antibiotics" title=" antibiotics"> antibiotics</a>, <a href="https://publications.waset.org/abstracts/search?q=drug%20resistance" title=" drug resistance"> drug resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=horizontal%20gene%20transfer" title=" horizontal gene transfer"> horizontal gene transfer</a> </p> <a href="https://publications.waset.org/abstracts/43006/antibiotic-susceptibility-profile-and-horizontal-gene-transfer-in-pseudomonas-sp-isolated-from-clinical-specimens" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43006.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">345</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">456</span> A Prospective Study on the Pattern of Antibiotics Use and Prevalence of Multidrug Resistant Escherichia Coli in Poultry Chickens and Its Correlation with Urinary Tract Infection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stelvin%20Sebastian">Stelvin Sebastian</a>, <a href="https://publications.waset.org/abstracts/search?q=Andriya%20Annie%20Tom"> Andriya Annie Tom</a>, <a href="https://publications.waset.org/abstracts/search?q=Joyalanna%20Babu"> Joyalanna Babu</a>, <a href="https://publications.waset.org/abstracts/search?q=Merin%20Joshy"> Merin Joshy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: The worldwide increase in the use of antibiotics in poultry and livestock industry to treat and prevent bacterial diseases and as growth promoters in feeds has led to the problem of development of antibiotic resistance both in animals and human population. Aim: To study the pattern of antibiotic use and prevalence of multidrug-resistant Escherichia coli in poultry chickens in selected farms in Muvattupuzha and to compare the spread of multidrug-resistant bacteria from poultry environment to UTI patients. Methodology: Two farms from each of 6 localities in Muvattupuzha were selected. A questionnaire on the pattern of antibiotic use and various farming practices were surveyed from farms. From each farm, 60samples of fresh fecal matter, litter from inside, litter from the outside shed, agricultural soil and control soil were collected, and antimicrobial susceptibility testing of E. coli was done. Antibiogram of UTI patients was collected from the secondary care hospital included in the study, and those were compared with resistance patterns of poultry samples. Results: From survey response antibiotics such as ofloxacin, enrofloxacin, levofloxacin, ciprofloxacin, colistin, ceftriaxone, neomycin, cephalexin, and oxytetracycline were used for treatment and prevention of infections in poultry. 31of 48 samples (51.66%) showed E. coli growth. 7 of 15 antibiotics (46.6%) showed resistance. Ampicillin, amoxicillin, meropenem, tetracycline showed 100% resistance to all samples. Statistical analysis confirmed similar resistance pattern in the poultry environment and UTI patients for antibiotics such as ampicillin, amoxicillin, amikacin, and ofloxacin. Conclusion: E. coli were resistant not only to extended-spectrum beta-lactams but also to carbapenems, which may be disseminated to the environment where litter was used as manure. This may due to irrational use of antibiotics in chicken or from their use in poultry feed as growth promoters. The study concludes the presence of multidrug-resistant E.coli in poultry and its spread to environment and humans, which may cause potentially serious implications for human health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multidrug%20resistance" title="multidrug resistance">multidrug resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=escherichia%20coli" title=" escherichia coli"> escherichia coli</a>, <a href="https://publications.waset.org/abstracts/search?q=urinary%20tract%20infection" title=" urinary tract infection"> urinary tract infection</a>, <a href="https://publications.waset.org/abstracts/search?q=poultry" title=" poultry"> poultry</a> </p> <a href="https://publications.waset.org/abstracts/111624/a-prospective-study-on-the-pattern-of-antibiotics-use-and-prevalence-of-multidrug-resistant-escherichia-coli-in-poultry-chickens-and-its-correlation-with-urinary-tract-infection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111624.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">155</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">455</span> Six Years Antimicrobial Resistance Trends among Bacterial Isolates in Amhara National Regional State, Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asrat%20Agalu%20Abejew">Asrat Agalu Abejew</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Antimicrobial resistance (AMR) is a silent tsunami and one of the top global threats to health care and public health. It is one of the common agendas globally and in Ethiopia. Emerging AMR will be a double burden to Ethiopia, which is facing a series of problems from infectious disease morbidity and mortality. In Ethiopia, although there are attempts to document AMR in healthcare institutions, comprehensive and all-inclusive analysis is still lacking. Thus, this study is aimed to determine trends in AMR from 2016-2021. Methods: A retrospective analysis of secondary data recorded in the Amhara Public Health Institute (APHI) from 2016 to 2021 G.C was conducted. Blood, Urine, Stool, Swabs, Discharge, body effusions, and other Microbiological specimens were collected from each study participants, and Bacteria identification and Resistance tests were done using the standard microbiologic procedure. Data was extracted from excel in August 2022, Trends in AMR were analyzed, and the results were described. In addition, the chi-square (X2) test and binary logistic regression were used, and a P. value < 0.05 was used to determine a significant association. Results: During 6 years period, there were 25143 culture and susceptibility tests. Overall, 265 (46.2%) bacteria were resistant to 2-4 antibiotics, 253 (44.2%) to 5-7 antibiotics, and 56 (9.7%) to >=8 antibiotics. The gram-negative bacteria were 166 (43.9%), 155 (41.5%), and 55 (14.6%) resistant to 2-4, 5-7, and ≥8 antibiotics, respectively, whereas 99(50.8%), 96(49.2% and 1 (0.5%) of gram-positive bacteria were resistant to 2-4, 5-7 and ≥8 antibiotics respectively. K. pneumonia 3783 (15.67%) and E. coli 3199 (13.25%) were the most commonly isolated bacteria, and the overall prevalence of AMR was 2605 (59.9%), where K. pneumonia 743 (80.24%), E. cloacae 196 (74.81%), A. baumannii 213 (66.56%) being the most common resistant bacteria for antibiotics tested. Except for a slight decline during 2020 (6469 (25.4%)), the overall trend of AMR is rising from year to year, with a peak in 2019 (8480 (33.7%)) and in 2021 (7508 (29.9%). If left un-intervened, the trend in AMR will increase by 78% of variation from the study period, as explained by the differences in years (R2=0.7799). Ampicillin, Augmentin, ciprofloxacin, cotrimoxazole, tetracycline, and Tobramycin were almost resistant to common bacteria they were tested. Conclusion: AMR is linearly increasing during the last 6 years. If left as it is without appropriate intervention after 15 years (2030 E.C), AMR will increase by 338.7%. A growing number of multi-drug resistant bacteria is an alarm to awake policymakers and those who do have the concern to intervene before it is too late. This calls for a periodic, integrated, and continuous system to determine the prevalence of AMR in commonly used antibiotics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AMR" title="AMR">AMR</a>, <a href="https://publications.waset.org/abstracts/search?q=trend" title=" trend"> trend</a>, <a href="https://publications.waset.org/abstracts/search?q=pattern" title=" pattern"> pattern</a>, <a href="https://publications.waset.org/abstracts/search?q=MDR" title=" MDR"> MDR</a> </p> <a href="https://publications.waset.org/abstracts/159598/six-years-antimicrobial-resistance-trends-among-bacterial-isolates-in-amhara-national-regional-state-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159598.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">76</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">454</span> Physico-Chemical Characterization of the Essential Oil of Daucus carota</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nassima%20Behidj-Benyounes">Nassima Behidj-Benyounes</a>, <a href="https://publications.waset.org/abstracts/search?q=Thoraya%20Dahmene"> Thoraya Dahmene</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Benyounes%20Nadjiba%20Chebouti1and%20F%2FZohra%20Bissaad"> Khaled Benyounes Nadjiba Chebouti1and F/Zohra Bissaad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Essential oils have a significant antimicrobial activity.

No previous studies are registered yet in Syrian children. Methods: Specimens were isolated from the oral cavity of pediatric patients, then in-vitro study is applied on locally manufactured liquid pediatric antibiotic drugs, containing natural or synthetic sweeteners. The selected antibiotics are Ampicillin (sucrose), Amoxicillin (sucrose), Amoxicillin + Flucloxacillin (sorbitol), Amoxicillin+Clavulanic acid (Sorbitol or sucrose). These antibiotics have a known inhibitory effect on gram positive aerobic/anaerobic bacteria especially Streptococcus mutans strains in children’s oral biofilm. Five colonies are studied with each antibiotic. Saturated antibiotics were spread on a 6mm diameter filter disc. Incubated culture media were compared with each other and with the control antibiotic discs. Results were evaluated by measuring the diameter of the inhibition zones. The control group of antibiotic discs was resourced from Abtek Biologicals Ltd. Results: The diameter of inhibition zones around discs of antibiotics sweetened with sorbitol was larger than those sweetened with sucrose. The effect was most important when comparing Amoxicillin + Clavulanic Acid (sucrose 25mm; versus sorbitol 27mm). The highest inhibitory effect was observed with the usage of Amoxicillin + Flucloxacillin sweetened with sorbitol (38mm). Whereas the lowest inhibitory effect was observed with Amoxicillin and Ampicillin sweetened with sucrose (22mm and 21mm). Conclusion: The results of this study indicate that although all selected antibiotic produced an inhibitory effect on S. mutans, sucrose weakened the inhibitory action of the antibiotic to varying degrees, meanwhile antibiotic formulations containing sorbitol simulated the effects of the control antibiotic. This study calls attention to effects of sweeteners included in pediatric drugs on the oral hygiene and tooth decay. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pediatric" title="pediatric">pediatric</a>, <a href="https://publications.waset.org/abstracts/search?q=dentistry" title=" dentistry"> dentistry</a>, <a href="https://publications.waset.org/abstracts/search?q=antibiotics" title=" antibiotics"> antibiotics</a>, <a href="https://publications.waset.org/abstracts/search?q=streptococcus%20mutans" title=" streptococcus mutans"> streptococcus mutans</a>, <a href="https://publications.waset.org/abstracts/search?q=biofilm" title=" biofilm"> biofilm</a>, <a href="https://publications.waset.org/abstracts/search?q=sucrose" title=" sucrose"> sucrose</a>, <a href="https://publications.waset.org/abstracts/search?q=sugar%20free" title=" sugar free"> sugar free</a> </p> <a href="https://publications.waset.org/abstracts/176094/effect-of-locally-produced-sweetened-pediatric-antibiotics-on-streptococcus-mutans-isolated-from-the-oral-cavity-of-pediatric-patients-in-syria-in-vitro-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176094.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">72</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">452</span> The Need for a One Health and Welfare Approach to Industrial Animal Farming</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Clinton%20Adas">Clinton Adas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Industrial animal farming contributes to numerous problems that humans face, and among these, antimicrobial resistance (AMR) has been identified by the World Health Organisation as a real possibility for the 21st Century. While numerous factors contribute to AMR, one of them is industrial animal farming and its effect on the food chain and environment. In 2017, livestock were given around 73% of all antibiotics worldwide to make them grow faster for profit purposes, to prevent illness caused by unhealthy living conditions, and to treat disease when it breaks out. Many of the antibiotics used provide little benefit to animals, and most are the same as those used by humans - including many deemed critical to human health that should be used sparingly. AMR contributes to millions of illnesses, and in 2019 was responsible for around 4.95 million deaths worldwide. It costs Europe around nine billion euros per year, while it costs the United States (US) around 20 billion dollars per year. While not a simple or quick solution, one way to begin to address the challenge of AMR and other harms from this type of farming is to focus on animal welfare as part of a One Health and Welfare approach, as better welfare requires less antibiotics usage, which may begin to break the cycle. <p class="card-text"><strong>Keywords:</strong> <a
