Radish roots with dark water-soaked lesions, maceration of tissue, and a foul odour were collected in the Kolar region, India. Two isolates were obtained from rotted samples that demonstrated morphologically unpigmented, white mucoid convex colonies on nutrient agar medium. The isolated bacteria (RDH1 and RDH3) were gram-negative, rod-shaped bacteria with biochemically distinct characteristics similar to the type culture of Enterobacter cloacae ATCC13047 and Bergy's handbook of determinative bacteriology. The 16s rRNA gene was used to identify Enterobacter species. On carrot, potato, tomato, chilli, bell pepper, knolkhol, cauliflower, cabbage, and cucumber slices, the Koch鈥瞫 postulates were fulfilled, and the pathogen was also pathogenic on radish, cauliflower, and cabbage seedlings were grown in a glasshouse. After 36 hours, both isolates exhibited a hypersensitive sensitivity to Nicotianatabacum. Semi-quantitative analysis revealed that cell wall degrading enzymes (CWDEs) such as pectin lyase, polygalacturonase, and cellulase (p=1.4e09) contributed to pathogenicity, whereas isolates produced biofilms (p=4.3e-11) that help in host adhesion. This is the first report in India of radish soft rot caused by E. cloacae. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=soft%20rot" title="soft rot">soft rot</a>, <a href="https://publications.waset.org/abstracts/search?q=enterobacter%20cloacae" title=" enterobacter cloacae"> enterobacter cloacae</a>, <a href="https://publications.waset.org/abstracts/search?q=16S%20rRNA" title="16S rRNA">16S rRNA</a>, <a href="https://publications.waset.org/abstracts/search?q=nicotiana%20tabacum" title=" nicotiana tabacum"> nicotiana tabacum</a>, <a href="https://publications.waset.org/abstracts/search?q=and%20pathogenicity" title=" and pathogenicity"> and pathogenicity</a> </p> <a href="https://publications.waset.org/abstracts/144195/identification-and-characterization-of-enterobacter-cloacae-new-soft-rot-causing-pathogen-of-radish-in-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144195.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">120</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">8</span> Molecular Epidemiology of Anthrax in Georgia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20G.%20Vepkhvadze">N.

Enukidze</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Anthrax is a fatal disease caused by strains of Bacillus anthracis, a spore-forming gram-positive bacillus that causes the disease anthrax in animals and humans. Anthrax is a zoonotic disease that is also well-recognized as a potential agent of bioterrorism. Infection in humans is extremely rare in the developed world and is generally due to contact with infected animals or contaminated animal products. Testing of this zoonotic disease began in 1907 in Georgia and is still being tested routinely to provide accurate information and efficient testing results at the State Laboratory of Agriculture of Georgia. Each clinical sample is analyzed by RT-PCR and bacteriology methods; this study used Real-Time PCR assays for the detection of B. anthracis that rely on plasmid-encoded targets with a chromosomal marker to correctly differentiate pathogenic strains from non-anthracis Bacillus species. During the period of 2015-2022, the State Laboratory of Agriculture (SLA) tested 250 clinical and environmental (soil) samples from several different regions in Georgia. In total, 61 out of the 250 samples were positive during this period. Based on the results, Anthrax cases are mostly present in Eastern Georgia, with a high density of the population of livestock, specifically in the regions of Kakheti and Kvemo Kartli. All laboratory activities are being performed in accordance with International Quality standards, adhering to biosafety and biosecurity rules by qualified and experienced personnel handling pathogenic agents. Laboratory testing plays the largest role in diagnosing animals with anthrax, which helps pertinent institutions to quickly confirm a diagnosis of anthrax and evaluate the epidemiological situation that generates important data for further responses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=animal%20disease" title="animal disease">animal disease</a>, <a href="https://publications.waset.org/abstracts/search?q=baccilus%20anthracis" title=" baccilus anthracis"> baccilus anthracis</a>, <a href="https://publications.waset.org/abstracts/search?q=edp" title=" edp"> edp</a>, <a href="https://publications.waset.org/abstracts/search?q=laboratory%20molecular%20diagnostics" title=" laboratory molecular diagnostics"> laboratory molecular diagnostics</a> </p> <a href="https://publications.waset.org/abstracts/155303/molecular-epidemiology-of-anthrax-in-georgia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155303.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">87</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">7</span> Histological and Microbiological Study about the Pneumonic Lungs of Calves Slaughtered in the Slaughterhouse of Batna</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamza%20Hadj%20Abdallah">Hamza Hadj Abdallah</a>, <a href="https://publications.waset.org/abstracts/search?q=Brahim%20Belabdi"> Brahim Belabdi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Respiratory disease is a dominant pathology in cattle. It causes mortality and especially morbidity and irreversible damage. Although the dairy herd is affected, it is essentially the lactating herd and especially young cattle either nursing or fattening that undergo the greatest economic impact. The objective of this study is to establish a microbiological diagnosis of bovine respiratory inffections from lung presented with gross lesions at the slaughter of Batna. A total of 124 samples (pharyngeal and nasal swabs and lung fragments) from 31 seven months old calves, with lung lesions was collected to determine possible correlations between etiologic agents and lesion types. The h茅patisation injury (or consolidation) was the major lesion (45.17%) preferentially localized in the right apical lobe. A diverse microbial flora (15 genera and 291 strains was isolated. The bacteria most frequently isolated are the Enterobacteriaceae (49.45%), Staphylococci (25.1%) followed by non Enterobacteriaceae bacilli represented by Pseudomonas (5.83%) and finally, Streptococcus (13.38 %). The pneumotropic bacteria (Pasteurellaaerogenes and Pasteurellapneumotropica) were isolated at a rate of 0.68%. The study of the sensitivity of some germs to antibiotics showed a sensitivity of 100% for ceftazidime. A very high sensitivity was also observed for kanamycin, Ciprofloxacin, Imepinem, Cefepime, Tobramycin and Gentamycin (between 90% and 97%). Strains of E. coli showed a sensitivity of 100% for Imepinem, while only 55.9% of the strains were sensitive to Ampicillin. The isolated Pasteurella exhibited excellent sensitivity (100%) for the antimicrobials used with the exception of Colistin and Ticarcillin-Clavulanic acid association which showed a sensitivity of 50%.This survey has demonstrated the strong spread of atypical pneumonia in cattle population (bulls) at the slaughterhouse of Batna justifying stunting and losses in cattle farms in the region.Thus, it was considered urgent to establish a profile of sensitivity of different germs to antibiotics isolated to limit this increasingly dreadful infection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pasteurella" title="Pasteurella">Pasteurella</a>, <a href="https://publications.waset.org/abstracts/search?q=enterobacteria" title=" enterobacteria"> enterobacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=bacteriology" title=" bacteriology"> bacteriology</a>, <a href="https://publications.waset.org/abstracts/search?q=pneumonia" title=" pneumonia"> pneumonia</a> </p> <a href="https://publications.waset.org/abstracts/58347/histological-and-microbiological-study-about-the-pneumonic-lungs-of-calves-slaughtered-in-the-slaughterhouse-of-batna" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58347.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">220</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">6</span> Case Report: Mandibular Area Abscesses in Calves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dovil%C4%97%20Ba%C4%8D%C4%97ninait%C4%97">Dovil臈 Ba膷臈ninait臈</a>, <a href="https://publications.waset.org/abstracts/search?q=Karina%20D%C5%BEermeikait%C4%97"> Karina D啪ermeikait臈</a>, <a href="https://publications.waset.org/abstracts/search?q=Justinas%20Kirvela"> Justinas Kirvela</a>, <a href="https://publications.waset.org/abstracts/search?q=Ram%C5%ABnas%20Antanaitis"> Ram奴nas Antanaitis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bacteria are often present in the mouth of cattle. Some of them can cause abscesses. Starting with severe swelling of the mouth, muscle spasm, or locked jaw, it can lead to inability to open its mouth, move the neck, cause pain while eating. While the calf is unable to eat properly, it becomes more susceptible to infectious diseases, lower weight gain can be observed. Abscesses can be considered as a continuum of oral disease, whereby early stages of the lumpy jaw could proceed from gingivitis to periodontal disease. In the event of tissue damage, bacteria can enter the bloodstream, even cause sepsis. The most common lesions occur when animals eat sharp grass, coarse fodder, sharp, piercing foreign bodies (this is especially common for calves when they are trying to eat inedible objects). A crossbred Holstein calf presented with a history of proliferative outgrowth in the mandibular region. On clinical examination, needle aspiration, mandibular swelling revealed sticky, white curd-like fluid containing. Pus bacteriology revealed gram-negative cocci. They were sensitive to amoxicillin, cephalexin, enrofloxacin, ceftiofur. Blood morphology was in physiological ranges. The calf was treated surgically. The growth was excised, the puss drained and the wound was flushed with potassium permanganate solution (0,01%). A week after clinical surgery examination was performed. The swelling was decreased. Superficial bacterial infections are often associated with poor hygiene, which should be improved before treatment is commenced. Clipping away dirty hair and gently washing affected areas of skin daily with solutions such as povidone-iodine, potassium permanganate is effective. Appropriate antibiotic therapy, based on sensitivity testing, may be used where there is evidence of systemic illness. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=calf" title="calf">calf</a>, <a href="https://publications.waset.org/abstracts/search?q=abscess" title=" abscess"> abscess</a>, <a href="https://publications.waset.org/abstracts/search?q=lumpy%20jaw" title=" lumpy jaw"> lumpy jaw</a>, <a href="https://publications.waset.org/abstracts/search?q=pus" title=" pus"> pus</a>, <a href="https://publications.waset.org/abstracts/search?q=Streptococcus" title=" Streptococcus"> Streptococcus</a>, <a href="https://publications.waset.org/abstracts/search?q=Staphylococcus" title=" Staphylococcus"> Staphylococcus</a>, <a href="https://publications.waset.org/abstracts/search?q=Actinobacillus" title=" Actinobacillus"> Actinobacillus</a>, <a href="https://publications.waset.org/abstracts/search?q=infection" title=" infection"> infection</a> </p> <a href="https://publications.waset.org/abstracts/143420/case-report-mandibular-area-abscesses-in-calves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143420.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">279</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">5</span> GC-MS-Based Untargeted Metabolomics to Study the Metabolism of Pectobacterium Strains</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Magdalena%20Smoktunowicz">Magdalena Smoktunowicz</a>, <a href="https://publications.waset.org/abstracts/search?q=Renata%20Wawrzyniak"> Renata Wawrzyniak</a>, <a href="https://publications.waset.org/abstracts/search?q=Malgorzata%20Waleron"> Malgorzata Waleron</a>, <a href="https://publications.waset.org/abstracts/search?q=Krzysztof%20Waleron"> Krzysztof Waleron</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Pectobacterium spp. were previously classified into the Erwinia genus founded in 1917 to unite at that time all Gram-negative, fermentative, nonsporulating and peritrichous flagellated plant pathogenic bacteria. After work of Waldee (1945), on Approved Lists of Bacterial Names and bacteriology manuals in 1980, they were described either under the species named Erwinia or Pectobacterium. The Pectobacterium genus was formally described in 1998 of 265 Pectobacterium strains. Currently, there are 21 species of Pectobacterium bacteria, including Pectobacterium betavasculorum since 2003, which caused soft rot on sugar beet tubers. Based on the biochemical experiments carried out for this, it is known that these bacteria are gram-negative, catalase-positive, oxidase-negative, facultatively anaerobic, using gelatin and causing symptoms of soft rot on potato and sugar beet tubers. The mere fact of growing on sugar beet may indicate a metabolism characteristic only for this species. Metabolomics, broadly defined as the biology of the metabolic systems, which allows to make comprehensive measurements of metabolites. Metabolomics, in combination with genomics, are complementary tools for the identification of metabolites and their reactions, and thus for the reconstruction of metabolic networks. The aim of this study was to apply the GC-MS-based untargeted metabolomics to study the metabolism of P. betavasculorum in different growing conditions. The metabolomic profiles of biomass and biomass media were determined. For sample preparation the following protocol was used: extraction with 900 碌l of methanol: chloroform: water mixture (10: 3: 1, v: v) were added to 900 碌l of biomass from the bottom of the tube and up to 900 碌l of nutrient medium from the bacterial biomass. After centrifugation (13,000 x g, 15 min, 4oC), 300碌L of the obtained supernatants were concentrated by rotary vacuum and evaporated to dryness. Afterwards, two-step derivatization procedure was performed before GC-MS analyses. The obtained results were subjected to statistical calculations with the use of both uni- and multivariate tests. The obtained results were evaluated using KEGG database, to asses which metabolic pathways are activated and which genes are responsible for it, during the metabolism of given substrates contained in the growing environment. The observed metabolic changes, combined with biochemical and physiological tests, may enable pathway discovery, regulatory inference and understanding of the homeostatic abilities of P. betavasculorum. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=GC-MS%20chromatograpfy" title="GC-MS chromatograpfy">GC-MS chromatograpfy</a>, <a href="https://publications.waset.org/abstracts/search?q=metabolomics" title=" metabolomics"> metabolomics</a>, <a href="https://publications.waset.org/abstracts/search?q=metabolism" title=" metabolism"> metabolism</a>, <a href="https://publications.waset.org/abstracts/search?q=pectobacterium%20strains" title=" pectobacterium strains"> pectobacterium strains</a>, <a href="https://publications.waset.org/abstracts/search?q=pectobacterium%20betavasculorum" title=" pectobacterium betavasculorum"> pectobacterium betavasculorum</a> </p> <a href="https://publications.waset.org/abstracts/155862/gc-ms-based-untargeted-metabolomics-to-study-the-metabolism-of-pectobacterium-strains" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155862.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">78</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">4</span> Detection and Identification of Antibiotic Resistant Bacteria Using Infra-Red-Microscopy and Advanced Multivariate Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Uraib%20Sharaha">Uraib Sharaha</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Salman"> Ahmad Salman</a>, <a href="https://publications.waset.org/abstracts/search?q=Eladio%20Rodriguez-Diaz"> Eladio Rodriguez-Diaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Elad%20Shufan"> Elad Shufan</a>, <a href="https://publications.waset.org/abstracts/search?q=Klaris%20Riesenberg"> Klaris Riesenberg</a>, <a href="https://publications.waset.org/abstracts/search?q=Irving%20J.%20Bigio"> Irving J.

However, the increasing resistance of bacteria to a broad spectrum of commonly used antibiotics has become a global health-care problem. Rapid determination of antimicrobial susceptibility of a clinical isolate is often crucial for the optimal antimicrobial therapy of infected patients and in many cases can save lives. The conventional methods for susceptibility testing like disk diffusion are time-consuming and other method including E-test, genotyping are relatively expensive. Fourier transform infrared (FTIR) microscopy is rapid, safe, and low cost method that was widely and successfully used in different studies for the identification of various biological samples including bacteria. The new modern infrared (IR) spectrometers with high spectral resolution enable measuring unprecedented biochemical information from cells at the molecular level. Moreover, the development of new bioinformatics analyses combined with IR spectroscopy becomes a powerful technique, which enables the detection of structural changes associated with resistivity. The main goal of this study is to evaluate the potential of the FTIR microscopy in tandem with machine learning algorithms for rapid and reliable identification of bacterial susceptibility to antibiotics in time span of few minutes. The bacterial samples, which were identified at the species level by MALDI-TOF and examined for their susceptibility by the routine assay (micro-diffusion discs), are obtained from the bacteriology laboratories in Soroka University Medical Center (SUMC). These samples were examined by FTIR microscopy and analyzed by advanced statistical methods. Our results, based on 550 E.coli samples, were promising and showed that by using infrared spectroscopic technique together with multivariate analysis, it is possible to classify the tested bacteria into sensitive and resistant with success rate higher than 85% for eight different antibiotics. Based on these preliminary results, it is worthwhile to continue developing the FTIR microscopy technique as a rapid and reliable method for identification antibiotic susceptibility. <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=E.%20coli" title=" E. coli"> E. coli</a>, <a href="https://publications.waset.org/abstracts/search?q=FTIR" title=" FTIR"> FTIR</a>, <a href="https://publications.waset.org/abstracts/search?q=multivariate%20analysis" title=" multivariate analysis"> multivariate analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=susceptibility" title=" susceptibility"> susceptibility</a> </p> <a href="https://publications.waset.org/abstracts/66942/detection-and-identification-of-antibiotic-resistant-bacteria-using-infra-red-microscopy-and-advanced-multivariate-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66942.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">265</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">3</span> Tuberculosis : Still a Nightmare for Third World Countries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Younas">Muhammad Younas</a>, <a href="https://publications.waset.org/abstracts/search?q=Zimal%20Naveed"> Zimal Naveed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction : TB is caused by the bacillus Mycobacterium tuberculosis, which is spread when people who are sick with TB expel bacteria into the air (e.g. by coughing). The 30 high TB burden countries accounted for 87% of all estimated incident cases worldwide, and eight of these countries accounted for more than two thirds of the global total: India (27%), Indonesia (10%), China (7.1%), the Philippines (7.0%), Pakistan (5.7%), Nigeria (4.5%), Bangladesh (3.6%) and the Democratic Republic of the Congo (3.0%). Objective : To analyze prevalence of tuberculosis among the people who presented at THQ hospital Bhalwal between April 2024 to June 2024. Method : Total of 9200 patients presented in the OPD of THQ hospital Bhalwal were included in the study. These presumed cases underwent diagnostic testing by sputum for AFB, Gene expert and chest x rays. The data was then classified based Pulmonary and Extra-pulmonary TB disease and further classified on the basis of bacteriology positive and clinically diagnosed TB. The registered TB cases were then classified in 8 age groups in years and according to the gender. All the registered TB cases were then tested for HIV to observe the relation between Tuberculosis and HIV. Results : The total of 9200 patients presented to OPD during the period of 3 months between April 2024 to June 2024. Total registered cases of Tuberculosis were 161 (comprising 153 new cases and 8 cases after treatment failure). Out of the new cases 83 were males and 70 female cases were identified. The majority of males that were identified lies between age 55-64 and 65 and above while the majority of females that were diagnosed lies in the age group of 5-14 and 15-24. All the registered cases were then tested for HIV but none of them were found to be positive. Conclusion : According to World Health Organisation Global Tuberculosis Report, the incidence of Tubeculosis per 100000 people was 258, equivalent to 0.258 %. However, the study reveals an exceptionally high frequency of TB cases. The prevalence of Tuberculosis per 100000 people was found to be 1750 which is equivalent to 1.75 %. The study revealed that larger proportion of the population is currently affected by TB compared to the global average incidence reported by the WHO. The findings of the study indicates that the prevalence of tuberculosis (TB) among females is most common in the younger population, specifically between the ages of 5 to 24, and particularly within the peak fertility age group of 15 to 24 years. The health of women in their peak fertility years is crucial for maternal and child health outcomes. This highlights the need for targeted public health interventions in this area to manage and reduce the burden of TB. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AGE" title="AGE">AGE</a>, <a href="https://publications.waset.org/abstracts/search?q=AFB" title=" AFB"> AFB</a>, <a href="https://publications.waset.org/abstracts/search?q=female" title=" female"> female</a>, <a href="https://publications.waset.org/abstracts/search?q=male" title=" male"> male</a> </p> <a href="https://publications.waset.org/abstracts/189030/tuberculosis-still-a-nightmare-for-third-world-countries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189030.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">38</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">2</span> From Primer Generation to Chromosome Identification: A Primer Generation Genotyping Method for Bacterial Identification and Typing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wisam%20H.%20Benamer">Wisam H.

Hence, advancement in the required technology is desirable to improve timing, accuracy and quality. Even with the current advances in methods used for both phenotypic and genotypic identification of bacteria the need is there to develop method(s) that enhance the outcome of bacteriology laboratories in accuracy and time. The hypothesis introduced here is based on the assumption that the chromosome of any bacteria contains unique sequences that can be used for its identification and typing. The outcome of a pilot study designed to test this hypothesis is reported in this manuscript. Methods: The complete chromosome sequences of several bacterial species were downloaded to use as search targets for unique sequences. Visual basic and SQL server (2014) were used to generate a complete set of 18-base long primers, a process started with reverse translation of randomly chosen 6 amino acids to limit the number of the generated primers. In addition, the software used to scan the downloaded chromosomes using the generated primers for similarities was designed, and the resulting hits were classified according to the number of similar chromosomal sequences, i.e., unique or otherwise. Results: All primers that had identical/similar sequences in the selected genome sequence(s) were classified according to the number of hits in the chromosomes search. Those that were identical to a single site on a single bacterial chromosome were referred to as unique. On the other hand, most generated primers sequences were identical to multiple sites on a single or multiple chromosomes. Following scanning, the generated primers were classified based on ability to differentiate between medically important bacterial and the initial results looks promising. Conclusion: A simple strategy that started by generating primers was introduced; the primers were used to screen bacterial genomes for match. Primer(s) that were uniquely identical to specific DNA sequence on a specific bacterial chromosome were selected. The identified unique sequence can be used in different molecular diagnostic techniques, possibly to identify bacteria. In addition, a single primer that can identify multiple sites in a single chromosome can be exploited for region or genome identification. Although genomes sequences draft of isolates of organism DNA enable high throughput primer design using alignment strategy, and this enhances diagnostic performance in comparison to traditional molecular assays. In this method the generated primers can be used to identify an organism before the draft sequence is completed. In addition, the generated primers can be used to build a bank for easy access of the primers that can be used to identify bacteria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bacteria%20chromosome" title="bacteria chromosome">bacteria chromosome</a>, <a href="https://publications.waset.org/abstracts/search?q=bacterial%20identification" title=" bacterial identification"> bacterial identification</a>, <a href="https://publications.waset.org/abstracts/search?q=sequence" title=" sequence"> sequence</a>, <a href="https://publications.waset.org/abstracts/search?q=primer%20generation" title=" primer generation"> primer generation</a> </p> <a href="https://publications.waset.org/abstracts/57860/from-primer-generation-to-chromosome-identification-a-primer-generation-genotyping-method-for-bacterial-identification-and-typing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57860.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">193</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">1</span> Detection and Identification of Antibiotic Resistant UPEC Using FTIR-Microscopy and Advanced Multivariate Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Uraib%20Sharaha">Uraib Sharaha</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Salman"> Ahmad Salman</a>, <a href="https://publications.waset.org/abstracts/search?q=Eladio%20Rodriguez-Diaz"> Eladio Rodriguez-Diaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Elad%20Shufan"> Elad Shufan</a>, <a href="https://publications.waset.org/abstracts/search?q=Klaris%20Riesenberg"> Klaris Riesenberg</a>, <a href="https://publications.waset.org/abstracts/search?q=Irving%20J.%20Bigio"> Irving J.

However, the increasing resistance of bacteria to a broad spectrum of commonly used antibiotics has become a global healthcare problem. Many antibiotics had lost their effectiveness since the beginning of the antibiotic era because many bacteria have adapted defenses against these antibiotics. Rapid determination of antimicrobial susceptibility of a clinical isolate is often crucial for the optimal antimicrobial therapy of infected patients and in many cases can save lives. The conventional methods for susceptibility testing require the isolation of the pathogen from a clinical specimen by culturing on the appropriate media (this culturing stage lasts 24 h-first culturing). Then, chosen colonies are grown on media containing antibiotic(s), using micro-diffusion discs (second culturing time is also 24 h) in order to determine its bacterial susceptibility. Other methods, genotyping methods, E-test and automated methods were also developed for testing antimicrobial susceptibility. Most of these methods are expensive and time-consuming. Fourier transform infrared (FTIR) microscopy is rapid, safe, effective and low cost method that was widely and successfully used in different studies for the identification of various biological samples including bacteria; nonetheless, its true potential in routine clinical diagnosis has not yet been established. The new modern infrared (IR) spectrometers with high spectral resolution enable measuring unprecedented biochemical information from cells at the molecular level. Moreover, the development of new bioinformatics analyses combined with IR spectroscopy becomes a powerful technique, which enables the detection of structural changes associated with resistivity. The main goal of this study is to evaluate the potential of the FTIR microscopy in tandem with machine learning algorithms for rapid and reliable identification of bacterial susceptibility to antibiotics in time span of few minutes.
