It is a predecessor of M. avium complex (MAC). Whole genome analysis and growth kinetics studies have placed MIP in between pathogenic and non-pathogenic species. It shares significant antigenic repertoire with M. tuberculosis and have unique immunomodulatory properties. MIP provides better protection than BCG against pulmonary tuberculosis in animal models. Immunization with MIP by aerosol route provides significantly higher protection as compared to immunization by subcutaneous (s.c.) route. However, mechanism behind differential protection has not been studied. In this study, using mice model we have evaluated and compared the M.tb specific immune response in lung compartments (airway lumen / lung interstitium) as well as spleen following MIP immunization via nasal (i.n.) and s.c. route. MIP i.n. vaccination resulted in increased seeding of memory T cells (CD4+ and CD8+ T-cells) in the airway lumen. Frequency of CD4+ T cells expressing Th1 migratory marker (CXCR3) and activation marker (CD69) were also high in airway lumen of MIP i.n. group. Significantly high ex vivo secretion of cytokines- IFN-, IL-12, IL-17 and TNF- from cells of airway luminal spaces provides evidence of antigen-specific lung immune response, besides generating systemic immunity comparable to MIP s.c. group. Analysis of T cell response on per cell basis revealed that antigen specific T-cells of MIP i.n. group were functionally superior as higher percentage of these cells simultaneously secreted IFN-gamma, IL-2 and TNF-alpha cytokines as compared to MIP s.c. group. T-cells secreting more than one of the cytokines simultaneously are believed to have robust effector response and crucial for protection, compared with single cytokine secreting T-cells. Adoptive transfer of airway luminal T-cells from MIP i.n. group into trachea of naive B6 mice revealed that MIP induced CD8 T-cells play crucial role in providing long term protection. Thus the study demonstrates that MIP intranasal vaccination induces M.tb specific memory T-cells in the airway lumen that results in an early and robust recall response against M.tb infection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=airway%20lumen" title="airway lumen">airway lumen</a>, <a href="https://publications.waset.org/abstracts/search?q=Mycobacterium%20indicus%20pranii" title=" Mycobacterium indicus pranii"> Mycobacterium indicus pranii</a>, <a href="https://publications.waset.org/abstracts/search?q=Th1%20migratory%20markers" title=" Th1 migratory markers"> Th1 migratory markers</a>, <a href="https://publications.waset.org/abstracts/search?q=vaccination" title=" vaccination"> vaccination</a> </p> <a href="https://publications.waset.org/abstracts/84568/analysis-of-anti-tuberculosis-immune-response-induced-in-lungs-by-intranasal-immunization-with-mycobacterium-indicus-pranii" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84568.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">187</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">131</span> Immunomodulatory Role of Heat Killed Mycobacterium indicus pranii against Cervical Cancer </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Priyanka%20Bhowmik">Priyanka Bhowmik</a>, <a href="https://publications.waset.org/abstracts/search?q=Subrata%20Majumdar"> Subrata Majumdar</a>, <a href="https://publications.waset.org/abstracts/search?q=Debprasad%20Chattopadhyay"> Debprasad Chattopadhyay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Cervical cancer is the third major cause of cancer in women and the second most frequent cause of cancer related deaths causing 300,000 deaths annually worldwide. Evasion of immune response by Human Papilloma Virus (HPV), the key contributing factor behind cancer and pre-cancerous lesions of the uterine cervix, makes immunotherapy a necessity to treat this disease. Objective: A Heat killed fraction of Mycobacterium indicus pranii (MIP), a non-pathogenic Mycobacterium has been shown to exhibit cytotoxic effects on different cancer cells, including human cervical carcinoma cell line HeLa. However, the underlying mechanisms remain unknown. The aim of this study is to decipher the mechanism of MIP induced HeLa cell death. Methods: The cytotoxicity of Mycobacterium indicus pranii against HeLa cells was evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Apoptosis was detected by annexin V and Propidium iodide (PI) staining. The assessment of reactive oxygen species (ROS) generation and cell cycle analysis were measured by flow cytometry. The expression of apoptosis associated genes was analyzed by real time PCR. Result: MIP could inhibit the proliferation of HeLa cell in a time and dose dependent manner but caused minor damage to normal cells. The induction of apoptosis was confirmed by the cell surface presentation of phosphatidyl serine, DNA fragmentation, and mitochondrial damage. MIP caused very early (as early as 30 minutes) transcriptional activation of p53, followed by a higher activation (32 fold) at 24 hours suggesting prime importance of p53 in MIP-induced apoptosis in HeLa cell. The up regulation of p53 dependent pro-apoptotic genes Bax, Bak, PUMA, and Noxa followed a lag phase that was required for the transcriptional p53 program. MIP also caused the transcriptional up regulation of Toll like receptor 2 and 4 after 30 minutes of MIP treatment suggesting recognition of MIP by toll like receptors. Moreover, MIP caused the inhibition of expression of HPV anti apoptotic gene E6, which is known to interfere with p53/PUMA/Bax apoptotic cascade. This inhibition might have played a role in transcriptional up regulation of PUMA and subsequently apoptosis. ROS was generated transiently which was concomitant with the highest transcription activation of p53 suggesting a plausible feedback loop network of p53 and ROS in the apoptosis of HeLa cells. Scavenger of ROS, such as N-acetyl-L-cysteine, decreased apoptosis suggesting ROS is an important effector of MIP induced apoptosis. Conclusion: Taken together, MIP possesses full potential to be a novel therapeutic agent in the clinical treatment of cervical cancer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cancer" title="cancer">cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=mycobacterium" title=" mycobacterium"> mycobacterium</a>, <a href="https://publications.waset.org/abstracts/search?q=immunity" title=" immunity"> immunity</a>, <a href="https://publications.waset.org/abstracts/search?q=immunotherapy." title=" immunotherapy."> immunotherapy.</a> </p> <a href="https://publications.waset.org/abstracts/80727/immunomodulatory-role-of-heat-killed-mycobacterium-indicus-pranii-against-cervical-cancer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80727.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">249</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">130</span> Screening for Hit Identification against Mycobacterium abscessus </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jichan%20Jang">Jichan Jang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mycobacterium abscessus is a rapidly growing life-threatening mycobacterium with multiple drug-resistance mechanisms. In this study, we screened the library to identify active molecules targeting Mycobacterium abscessus using resazurin live/dead assays. In this screening assay, the Z-factor was 0.7, as an indication of the statistical confidence of the assay. A cut-off of 80% growth inhibition in the screening resulted in the identification of four different compounds at a single concentration (20 μM). Dose-response curves identified three different hit candidates, which generated good inhibitory curves. All hit candidates were expected to have different molecular targets. Thus, we found that compound X, identified, may be a promising candidate in the M. abscessus drug discovery pipeline. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mycobacterium%20abscessus" title="Mycobacterium abscessus">Mycobacterium abscessus</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%20discovery" title=" drug discovery"> drug discovery</a>, <a href="https://publications.waset.org/abstracts/search?q=emerging%20Pathogen" title=" emerging Pathogen"> emerging Pathogen</a> </p> <a href="https://publications.waset.org/abstracts/91908/screening-for-hit-identification-against-mycobacterium-abscessus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91908.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">209</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">129</span> Exploring the Role of Immune-Modulators in Pathogen Recognition Receptor NOD2 Mediated Protection against Visceral Leishmaniasis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Junaid%20Jibran%20Jawed">Junaid Jibran Jawed</a>, <a href="https://publications.waset.org/abstracts/search?q=Prasanta%20Saini"> Prasanta Saini</a>, <a href="https://publications.waset.org/abstracts/search?q=Subrata%20Majumdar"> Subrata Majumdar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Leishmania donovani infection causes severe host immune-suppression through the modulation of pathogen recognition receptors. Apart from TLRs (Toll Like Receptor), recent studies focus on the important contribution of NLR (NOD-Like Receptor) family member NOD1 and NOD2 as these receptors are capable of triggering host innate immunity. The aim of this study was to decipher the role of NOD1/NOD2 receptors during experimental visceral leishmaniasis (VL) and the important link between host failure and parasite evasion strategy. Method: The status of NOD1 and NOD2 receptors were analysed in uninfected and infected cells through western blotting and RT-PCR. The active contributions of these receptors in reducing parasite burden were confirmed by siRNA mediated silencing, and over-expression studies and the parasite numbers were calculated through microscopic examination of the Giemsa-stained slides. In-vivo studies were done by using non-toxic dose of Mw (Mycobacterium indicus pranii), Ara-LAM(Arabinoasylated lipoarabinomannan) along with MDP (Muramyl dipeptide) administration. Result: Leishmania donovani infection of the macrophages reduced the expression of NOD2 receptors whereas NOD1 remain unaffected. MDP, a NOD2-ligand, treatment during over-expression of NOD2, reduced the parasite burden effectively which was associated with increased pro-inflammatory cytokine generation and NO production. In experimental mouse model, Ara-LAM treatment increased the expression of NOD2 and in combination with MDP it showed active therapeutic potential against VL and found to be more effective than Mw which was already reported to be involved in NOD2 modulation. Conclusion: This work explores the essential contribution of NOD2 during experimental VL and mechanistic understanding of Ara-LAM + MDP combination therapy to work against this disease and highlighted NOD2 as an essential therapeutic target. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ara-LAM%20%28Arabinoacylated%20Lipoarabinomannan%29" title="Ara-LAM (Arabinoacylated Lipoarabinomannan)">Ara-LAM (Arabinoacylated Lipoarabinomannan)</a>, <a href="https://publications.waset.org/abstracts/search?q=NOD2%20%28nucleotide%20binding%20oligomerization%20receptor%202%29" title=" NOD2 (nucleotide binding oligomerization receptor 2)"> NOD2 (nucleotide binding oligomerization receptor 2)</a>, <a href="https://publications.waset.org/abstracts/search?q=MDP%20%28muramyl%20di%20peptide%29" title=" MDP (muramyl di peptide)"> MDP (muramyl di peptide)</a>, <a href="https://publications.waset.org/abstracts/search?q=visceral%20Leishmaniasis" title=" visceral Leishmaniasis"> visceral Leishmaniasis</a> </p> <a href="https://publications.waset.org/abstracts/80536/exploring-the-role-of-immune-modulators-in-pathogen-recognition-receptor-nod2-mediated-protection-against-visceral-leishmaniasis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80536.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">175</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">128</span> Influence of Cyperus Rotundus Active Principles Inhibit Viral Multiplication and Stimulate Immune System in Indian White Shrimp Fenneropenaeus Indicus against White Spot Syndrome Virus Infection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thavasimuthu%20Citarasu">Thavasimuthu Citarasu</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariavincent%20Michaelbabu"> Mariavincent Michaelbabu</a>, <a href="https://publications.waset.org/abstracts/search?q=Vikram%20Vakharia"> Vikram Vakharia </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The rhizome of Java grass, Cyperus rotundus was extracted different organic polar and non-polar solvents and performed the in vitro antiviral and immunostimulant activities against White Spot Syndrome Virus (WSSV) and Vibrio harveyi respectively. Based on the initial screening the ethyl acetate extract of C. rotundus was strong activities and further it was purified through silica column chromatography and the fractions were screened again for antiviral and immunostimulant activity. Among the different fractions screened against the WSSV and V. harveyi, the fractions, F-III to FV had strong activities. In order to study the in vivo influence of C. rotundus, the fractions (F-III to FV) were pooled and delivered to the F. indicus through artificial feed for 30 days. After the feeding trail the experimental and control diet fed F. indicus were challenged with virulent WSSV and studied the survival, molecular diagnosis, biochemical, haematological and immunological parameters. Surprisingly, the pooled fractions (F-III to FV) incorporated diets helped to significantly (P < 0.01) suppressed viral multiplication, showed significant (P < 0.01) differences in protein and glucose levels, improved total haemocyte count (THC), coagulase activity, significantly increased (P < =0.001) prophenol oxidase and intracellular superoxide anion production compared to the control shrimps. Based on the results, C. rotundus extracts effectively suppressed WSSV multiplication and improve the immune system in F. indicus against WSSV infection and this knowledge will helps to develop novel drugs from C. rotundus against WSSV. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antiviral%20drugs" title="antiviral drugs">antiviral drugs</a>, <a href="https://publications.waset.org/abstracts/search?q=cyperus%20rotundus" title=" cyperus rotundus"> cyperus rotundus</a>, <a href="https://publications.waset.org/abstracts/search?q=fenneropenaeus%20indicus" title=" fenneropenaeus indicus"> fenneropenaeus indicus</a>, <a href="https://publications.waset.org/abstracts/search?q=WSSV" title=" WSSV"> WSSV</a> </p> <a href="https://publications.waset.org/abstracts/25193/influence-of-cyperus-rotundus-active-principles-inhibit-viral-multiplication-and-stimulate-immune-system-in-indian-white-shrimp-fenneropenaeus-indicus-against-white-spot-syndrome-virus-infection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25193.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">455</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">127</span> Prevalence of Mycobacterium Tuberculosis Infection and Rifampicin Resistance among Presumptive Tuberculosis Cases Visiting Tuberculosis Clinic of Adare General Hospital, Southern Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Degineh%20Belachew%20Andarge">Degineh Belachew Andarge</a>, <a href="https://publications.waset.org/abstracts/search?q=Tariku%20Lambiyo%20Anticho"> Tariku Lambiyo Anticho</a>, <a href="https://publications.waset.org/abstracts/search?q=Getamesay%20Mulatu%20Jara"> Getamesay Mulatu Jara</a>, <a href="https://publications.waset.org/abstracts/search?q=Musa%20Mohammed%20Ali"> Musa Mohammed Ali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Tuberculosis (TB) is a communicable chronic disease causedby Mycobacterium tuberculosis (MTB). About one-third of the world’s population is latently infected with MTB. TB is among the top 10 causes of mortality throughout the globe from a single pathogen. Objective: The aim of this study was to determine the prevalence of tuberculosis,rifampicin-resistant/multidrug-resistant Mycobacterium tuberculosis, and associated factors among presumptive tuberculosis cases attending the tuberculosis clinic of Adare General Hospital located in Hawassa city. Methods: A hospital-based cross-sectional study was conducted among 321 tuberculosis suspected patients from April toJuly 2018. Socio-demographic, environmental, and behavioral data were collected using a structured questionnaire. Sputumspecimens were analyzed using GeneXpert. Data entry was made using Epi info version 7 and analyzed by SPSS version 20. Logistic regression models were used to determine the risk factors. A p-value less than 0.05 was taken as a cut point. Results: In this study, the prevalence of Mycobacterium tuberculosis was 98 (30.5%) with 95% confidence interval (25.5–35.8), and the prevalence of rifampicin-resistant/multidrug-resistantMycobacterium tuberculosis among the 98 Mycobacteriumtuberculosis confirmed cases was 4 (4.1%). The prevalence of rifampicin-resistant/multidrug-resistant Mycobacterium tuberculosisamong the tuberculosis suspected patients was 1.24%. Participants who had a history of treatment with anti-tuberculosisdrugs were more likely to develop rifampicin-resistant/multidrug-resistant Mycobacterium tuberculosis. Conclusions: This study identified relatively high rifampicin-resistant/multidrug-resistant Mycobacterium tuberculosis amongtuberculosis suspected patients in the study area. Early detection of drug-resistant Mycobacterium tuberculosis should be givenenough attention to strengthen the management of tuberculosis cases and improve direct observation therapy short-course and eventually minimize the spread of rifampicin-resistant tuberculosis strain in the community. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rifampicin%20resistance" title="rifampicin resistance">rifampicin resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=mycobacterium%20tuberculosis" title=" mycobacterium tuberculosis"> mycobacterium tuberculosis</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20factors" title=" risk factors"> risk factors</a>, <a href="https://publications.waset.org/abstracts/search?q=prevalence%20of%20TB" title=" prevalence of TB"> prevalence of TB</a> </p> <a href="https://publications.waset.org/abstracts/151759/prevalence-of-mycobacterium-tuberculosis-infection-and-rifampicin-resistance-among-presumptive-tuberculosis-cases-visiting-tuberculosis-clinic-of-adare-general-hospital-southern-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151759.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">111</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">126</span> Dyeing with Natural Dye from Pterocarpus indicus Extract Using Eco-Friendly Mordants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ploysai%20Ohama">Ploysai Ohama</a>, <a href="https://publications.waset.org/abstracts/search?q=Nuttawadee%20Hanchengchai"> Nuttawadee Hanchengchai</a>, <a href="https://publications.waset.org/abstracts/search?q=Thiva%20Saksri"> Thiva Saksri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Natural dye extracted from Pterocarpus indicus was applied to a cotton fabric and silk yarn by dyeing processing different eco-friendly mordants.

Three filamentous fungi such as <em>Aspergillus oryzae</em>, <em>Mucor indicus</em>, and <em>Rhizopus oryzae</em> were investigated in this work. The SSL was diluted in order to obtain concentrations of 50, 60, 70, 80, and 90% and supplemented with two types of nutrients. The results from cultivations in shake flask showed that <em>A. oryzae</em> and <em>M. indicus</em> were not able to grow in pure SSL and SSL90% while <em>R. oryzae</em> could grow only in SSL50% and SSL60%. Cultivation with <em>A. oryzae</em> resulted in the highest yield of produced fungal biomass, while <em>R. oryzae</em> cultivation resulted in the lowest fungal biomass yield. Although, the mediums containing yeast extract, (NH<sub>4</sub>)<sub>2</sub>SO<sub>4</sub>, KH<sub>2</sub>PO<sub>4</sub>, CaCl<sub>2</sub>∙2H<sub>2</sub>O, and MgSO<sub>4</sub>∙7H<sub>2</sub>O as nutrients supplementations produced higher fungal biomass compared to the mediums containing NH<sub>4</sub>H<sub>2</sub>PO<sub>4</sub> and ammonia, but there was no significant difference between two types of nutrients in terms of sugars and acetic acid consumption rate. The sugars consumption in <em>M. indicus</em> cultivation was faster than <em>A. oryzae</em> and <em>R. oryzae</em> cultivation. Acetic acid present in SSL was completely consumed during cultivation of all fungi. <em>M. indicus</em> was the best and fastest ethanol producer from SSL among the fungi examined, when yeast extract and salts were used as nutrients supplementations. Furthermore, no further improvement in ethanol concentration and rate of sugars consumption was obtained in medium supplemented with NH<sub>4</sub>H<sub>2</sub>PO<sub>4</sub> and ammonia compared to medium containing yeast extract, (NH<sub>4</sub>)<sub>2</sub>SO<sub>4</sub>, KH<sub>2</sub>PO<sub>4</sub>, CaCl<sub>2</sub>∙2H<sub>2</sub>O, and MgSO<sub>4</sub>∙7H<sub>2</sub>O. On the other hand, the higher dilution of SSL resulted in a better fermentability, and better consumption of sugars and acetic acid. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ethanol" title="ethanol">ethanol</a>, <a href="https://publications.waset.org/abstracts/search?q=filamentous%20fungi" title=" filamentous fungi"> filamentous fungi</a>, <a href="https://publications.waset.org/abstracts/search?q=fungal%20biomass" title=" fungal biomass"> fungal biomass</a>, <a href="https://publications.waset.org/abstracts/search?q=spent%20sulfite%20liquor" title=" spent sulfite liquor"> spent sulfite liquor</a> </p> <a href="https://publications.waset.org/abstracts/53168/ethanol-and-biomass-production-from-spent-sulfite-liquor-by-filamentous-fungi" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53168.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">254</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">123</span> Inhibition of 3-Deoxy-D-Arabino-Heptulosonate 7-Phosphate Synthase from Mycobacterium Tuberculosis Using High Throughput Virtual Screening and Molecular Dynamics Studies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christy%20Rosaline">Christy Rosaline</a>, <a href="https://publications.waset.org/abstracts/search?q=Rathankar%20Roa"> Rathankar Roa</a>, <a href="https://publications.waset.org/abstracts/search?q=Waheeta%20Hopper"> Waheeta Hopper</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Persistence of tuberculosis, emergence of multidrug-resistance and extensively drug-resistant forms of the disease, has increased the interest in developing new antitubercular drugs.

It is hypothesized that given these morphological similarities, the genome of mycobacterium could have an impact on the development of Sarcoidosis. Identifying the potential correlation of these diseases may assist in the management of sarcoidosis. Herein, we aimed to inspect the lymph node biopsy of sarcoidosis patients for the existence of the HSP-65 mycobacterium DNA sequence. Methods: This cross-sectional survey was conducted on 1188 Sarcoidosis patients without active/latent tuberculosis infection who were diagnosed in Masih Daneshvari Hospital in Tehran, Iran, from January 2020 to January 2022. Trans-bronchial needle aspiration (TBNA) was performed due to bilateral hilar lymphadenopathy to take a specimen. Results: The under-evaluated patients were mainly women (N=815 (68.6%)), none-smoker (N=1016 (85.5%)), and middle-aged (50.1 (SD=4.22)) with average angiotensin-converting enzyme (ACE) index of 75.6 (SD=6.42). Dyslipidemias (n=314 (26.4%), Hypertension (n=295 (24.8%)), Diabetes mellitus (n=131 (11.0%)), and chronic heart diseases (n=97 (8.2%)) had the highest prevalence between comorbidities. Skin lesions (n= 655 (55.1%)), ophthalmic (n=341 (28.7%)), and cardiac involvement (n=229 (19.3%)) were obtained as the most common extra-pulmonary characteristics of the patients. Amongst 1188 enrolled patients who were not afflicted with Mycobacterium tuberculosis based on smear/culture essay, clinical symptoms, and Chest x-ray screening, 121 (10.2%) cases had detectable amplified DNA for Mycobacterium Tuberculosis extracted from mediastinal lung lymph nodes. Conclusion: In this survey, the mycobacterium genome was detected in almost 1 per 10 case biopsies of sarcoidosis. The remarkable number of cases (n=1188) evaluated in this study was the strength of this study which supported the hypothesis regarding sarcoidosis and mycobacterium genome correlation. Further investigation, such as case-control surveys, is required to better clarify this association. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mycobacterium%20tuberculosis" title="mycobacterium tuberculosis">mycobacterium tuberculosis</a>, <a href="https://publications.waset.org/abstracts/search?q=sarcoidosis" title=" sarcoidosis"> sarcoidosis</a>, <a href="https://publications.waset.org/abstracts/search?q=genome" title=" genome"> genome</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA" title=" DNA"> DNA</a>, <a href="https://publications.waset.org/abstracts/search?q=trans-bronchial%20needle%20aspiration" title=" trans-bronchial needle aspiration"> trans-bronchial needle aspiration</a> </p> <a href="https://publications.waset.org/abstracts/187424/mycobacterium-genome-extraction-from-lymph-nodes-of-sarcoidosis-cases-using-transbronchial-needle-aspiration-a-cross-sectional-descriptive-essay-on-1223-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187424.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">31</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">121</span> Identifying Pathogenic Mycobacterium Species Using Multiple Gene Phylogenetic Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lemar%20Blake">Lemar Blake</a>, <a href="https://publications.waset.org/abstracts/search?q=Chris%20Oura"> Chris Oura</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayanna%20C.%20N.%20Phillips%20Savage"> Ayanna C.

Mycobacteriosis with consistent hyphema, bilateral exophthalmia, open mouth gape and ocular lesions, were observed in various fish populations at the School of Veterinary Medicine, Aquaculture/Aquatic Animal Health Unit. Objective: To identify the species of Mycobacterium that is affecting aquarium fish at the School of Veterinary Medicine, Aquaculture/Aquatic Animal Health Unit. Method: A total of 13 fish samples were collected and analyzed via: Ziehl-Neelsen, conventional polymerase chain reaction (PCR) and real-time PCR. These tests were carried out simultaneously for confirmation. The following combination of conventional primers: 16s rRNA (564 bp), rpoB (396 bp), sod (408 bp) were used. Concatenation of the gene fragments was carried out to phylogenetically classify the organism. Results: Acid fast non-branching bacilli were detected in all samples from homogenized internal organs. All 13 acid fast samples were positive for Mycobacterium via real-time PCR. Partial gene sequences using all three primer sets were obtained from two samples and demonstrated a novel strain. A strain 99% related to Mycobacterium marinum was also confirmed in one sample, using 16srRNA and rpoB genes. The two novel strains were clustered with the rapid growers and strains that are known to affect humans. Conclusions: Phylogenetic analysis demonstrated two novel Mycobacterium strains with the potential of being zoonotic and one strain 99% related to Mycobacterium marinum. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=polymerase%20chain%20reaction" title="polymerase chain reaction">polymerase chain reaction</a>, <a href="https://publications.waset.org/abstracts/search?q=phylogenetic" title=" phylogenetic"> phylogenetic</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA%20sequencing" title=" DNA sequencing"> DNA sequencing</a>, <a href="https://publications.waset.org/abstracts/search?q=zoonotic" title=" zoonotic "> zoonotic </a> </p> <a href="https://publications.waset.org/abstracts/124273/identifying-pathogenic-mycobacterium-species-using-multiple-gene-phylogenetic-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124273.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">143</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">120</span> Genetic Diversity of Mycobacterium bovis and Its Zoonotic Potential in Ethiopia: A Systematic Review </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Begna%20Tulu">Begna Tulu</a>, <a href="https://publications.waset.org/abstracts/search?q=Gobena%20Ameni"> Gobena Ameni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Understanding the types of Mycobacterium bovis (M. bovis) strains circulating in a country and exploring its zoonotic potential has significant contribution in the effort to design control strategies. The main aim of this study was to review and compile the results of studies conducted on M. bovis genotyping and its zoonotic potential of M. bovis in Ethiopia. A systematic search and review of articles published on M. bovis strains in Ethiopia were made. PubMed and Google Scholar databases were considered for the search while the keywords used were 'Mycobacteria,' 'Mycobacterium bovis,' 'Bovine Tuberculosis' and 'Ethiopia.' Fourteen studies were considered in this review and a total of 31 distinct strains of M. bovis (N=211) were obtained; the most dominant strains were SB0133 (N=62, 29.4%), SB1176 (N=61, 28.9%), and followed by SB0134 and SB1476 each (N=18, 8.5%). The clustering rate of M. bovis strains was found to be 42.0%. On the other hand, 6 strains of M. bovis were reported from human namely; SB0665 (N=4), SB0303 (N=2), SB0982 (N=2), SB0133 (N=1), SB1176 (N=1), and 1 new strain. Similarly, a total of 8 strains (N=13) of M. tuberculosis bacteria were also identified from animal subjects; namely SIT149 (N=3), SIT1 (N=2), SIT1688 (n=2), SIT262 (N=2), SIT53 (N=1), SIT59 (N=1), and one new-Ethiopian strain. The result showed that the genetic diversity of M. bovis strains reported from Ethiopia are less diversified and highly clustered. And also the result underlines that there is an ongoing active transmission of M. bovis and M. tuberculosis between human and animals in Ethiopia because a significant number strains of both type of bacteria were reported from human and animals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mycobacterium%20bovis" title="mycobacterium bovis">mycobacterium bovis</a>, <a href="https://publications.waset.org/abstracts/search?q=Mycobacterium%20tuberculosis" title=" Mycobacterium tuberculosis"> Mycobacterium tuberculosis</a>, <a href="https://publications.waset.org/abstracts/search?q=zoonotic%20potential" title=" zoonotic potential"> zoonotic potential</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20diversity" title=" genetic diversity"> genetic diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=Ethiopia" title=" Ethiopia"> Ethiopia</a> </p> <a href="https://publications.waset.org/abstracts/105850/genetic-diversity-of-mycobacterium-bovis-and-its-zoonotic-potential-in-ethiopia-a-systematic-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105850.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">138</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">119</span> Changes in Fish and Shellfish in Thondamanaru Lagoon, Jaffna, Sri Lanka</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Piratheepa">S.

The identification of structural or functional defects in the mutant KatGs responsible for INH resistance remains as an area to be explored. In this connection, the differences in the binding affinity between wild-type (WT) and mutants of KatG were investigated, through the generation of three mutants of KatG, Ser315Thr [S315T], Ser315Asn [S315N], Ser315Arg [S315R] and a WT [S315]) with the help of software-MODELLER. The mutants were docked with INH using the software-GOLD. The affinity is lower for WT than mutant, suggesting the tight binding of INH with the mutant protein compared to WT type. These models provide the in silico evidence for the binding interaction of KatG with INH and implicate the basis for rationalization of INH resistance in naturally occurring KatG mutant strains of Mycobacterium tuberculosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mycobacterium%20tuberculosis" title="Mycobacterium tuberculosis">Mycobacterium tuberculosis</a>, <a href="https://publications.waset.org/abstracts/search?q=KatG" title=" KatG"> KatG</a>, <a href="https://publications.waset.org/abstracts/search?q=INH%20resistance" title=" INH resistance"> INH resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=mutants" title=" mutants"> mutants</a>, <a href="https://publications.waset.org/abstracts/search?q=modelling" title=" modelling"> modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=docking" title=" docking"> docking</a> </p> <a href="https://publications.waset.org/abstracts/6727/in-silico-analysis-of-isoniazid-resistance-in-mycobacterium-tuberculosis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6727.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">317</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">117</span> Detection of Mycobacteria spp by PCR in Raw Milk Samples Collected from Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shokoufeh%20Roudashti">Shokoufeh Roudashti</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahin%20Bahari"> Shahin Bahari</a>, <a href="https://publications.waset.org/abstracts/search?q=Fakhri%20Haghi"> Fakhri Haghi</a>, <a href="https://publications.waset.org/abstracts/search?q=Habib%20Zeighami"> Habib Zeighami</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghazal%20Naderi"> Ghazal Naderi</a>, <a href="https://publications.waset.org/abstracts/search?q=Paniz%20Shirmast"> Paniz Shirmast</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Mycobacterium tuberculosis complex (MTBC) causes tuberculosis (TB) in humans and animals. Mycobacterium MTBC is one of the most important species of zoonotic pathogens that can be transmitted from cattle to humans. The disease can transmit to human by direct contact with the infected animals, drinking unpasteurized milk and consumption of uncooked meat. The presence of these opportunistic, pathogenic bacteria in bovine milk has emerged as a public-health concern, especially among individuals who consume raw milk. Tuberculosis MTBC is the predominant infectious cause of morbidity and morality worldwide, It is estimated that one third of the world population (approx. 1.8 billion persons) is infected with M. tuberculosis and each year there are 8 million new cases worldwide. The aim of this study, to detect Mycobacterium MTBC in raw milk samples using polymerase chain reaction (PCR). Materials and Methods: In the present study, 60 raw milk samples were collected from rural areas in Zanjan, Iran. After extraction of DNAs and using special primers for Is6110 gene as a marker, PCR was applied to detect the presence or non-presence of the related gene. Results: According to the findings of this study, 8 (13.5 %) out of 60 milk samples were positive for Mycobacterium spp (P < 0.1). Conclusions: The Outbreak of genus Mycobacteria spp in milk samples were determined to be relatively high in Zanjan, Iran. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mycobacteria%20spp" title="Mycobacteria spp">Mycobacteria spp</a>, <a href="https://publications.waset.org/abstracts/search?q=raw%20milk" title=" raw milk"> raw milk</a>, <a href="https://publications.waset.org/abstracts/search?q=PCR" title=" PCR"> PCR</a>, <a href="https://publications.waset.org/abstracts/search?q=Zanjan" title=" Zanjan"> Zanjan</a> </p> <a href="https://publications.waset.org/abstracts/37406/detection-of-mycobacteria-spp-by-pcr-in-raw-milk-samples-collected-from-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37406.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">297</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">116</span> The Great Mimicker: A Case of Disseminated Tuberculosis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=W.%20Ling">W.

Central nervous system (CNS) infection by mycobacterium tuberculosis is one of the most devastating complications of tuberculosis. Although with advancement in medical fields, we are yet to understand the pathophysiology of how mycobacterium tuberculosis was able to cross the blood-brain barrier (BBB) and infect the CNS. CNS TB may present with nonspecific clinical symptoms which can mimic other diseases/conditions; this is what makes the diagnosis relatively difficult and challenging. Public health has to be informed and educated about the spread of TB, and early identification of TB is important as it is a curable disease. Case Report: A young 21-year-old Malay gentleman was initially presented to us with symptoms of ear discharge, tinnitus, and right-sided headache for the past one year. Further history reveals that the symptoms have been mismanaged and neglected over the period of 1 year. Initial investigation reveals features of inflammation of the ear. Further imaging showed the feature of chronic inflammation of the otitis media and atypical right cerebral abscess, which has the same characteristic features and consistency. He further underwent a biopsy, and results reveal positive Mycobacterium tuberculosis of the otitis media. With the results and the available imaging, we were certain that this is likely a case of disseminated tuberculosis causing CNS TB. Conclusion: We aim to highlight the challenge and difficult face in our health care system and public health in early identification and treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=central%20nervous%20system%20tuberculosis" title="central nervous system tuberculosis">central nervous system tuberculosis</a>, <a href="https://publications.waset.org/abstracts/search?q=intracranial%20tuberculosis" title=" intracranial tuberculosis"> intracranial tuberculosis</a>, <a href="https://publications.waset.org/abstracts/search?q=tuberculous%20encephalopathy" title=" tuberculous encephalopathy"> tuberculous encephalopathy</a>, <a href="https://publications.waset.org/abstracts/search?q=tuberculous%20meningitis" title=" tuberculous meningitis"> tuberculous meningitis</a> </p> <a href="https://publications.waset.org/abstracts/138049/the-great-mimicker-a-case-of-disseminated-tuberculosis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138049.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">189</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">115</span> Testing Immunochemical Method for the Bacteriological Diagnosis of Bovine Tuberculosis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Assiya%20Madenovna%20Borsynbayeva">Assiya Madenovna Borsynbayeva</a>, <a href="https://publications.waset.org/abstracts/search?q=Kairat%20Altynbekovich%20Turgenbayev"> Kairat Altynbekovich Turgenbayev</a>, <a href="https://publications.waset.org/abstracts/search?q=Nikolay%20Petrovich%20Ivanov"> Nikolay Petrovich Ivanov</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this article presents the results of rapid diagnostics of tuberculosis in comparison with classical bacteriological method.

Overweight in adults and stunting among preschool children have dramatically increased and become the main problems of malnutrition that should be solved immediately since they are directly related with the health status and productivity. Reformulation of food product by using the local sea resources called terasi shrimp (Acetes indicus) has a potential possibility in facing the DBM. A study was carried out in Indonesia to determine the acceptability of terasi shrimp powder through sensory evaluation. Terasi shrimps were processed into powder form through sun drying and pounding methods. The powder form was directly added in food as alternative seasonings and tested among stunted and normal preschool children. Meanwhile, a further processing method is given to the shrimp powder tested in overweight and normal-weighed adults. The shrimp powder was mixed with sago flour and formed into balls, then steamed for 15-20 minutes, and finally served as alternative snacks. Based on the sensory evaluation, the shrimp powder has a good acceptance in taste (54%), shape (60%), and color properties (63%), while the shrimp balls has a good acceptance in size (65%), shape (50%), color (48%), taste (40%), and texture (36%). Terasi shrimp powder can be stored for a month in room temperature. In addition, carried out chemical analysis revealed that terasi shrimp (Acetes indicus) has higher percentage of protein, calcium, and iron than other animal sources, but conversely contains zero sodium and very low percentage of fat. Terasi shrimp’s shell also contains a substance called chitosan which acts by forming gels in the intestinal tract to entrap lipids, thus interfering with their absorption. After going through some processing methods, the shrimp powder and balls did not show any significant changes in their nutrient contents. So that, terasi shrimp powder is good to be consumed not only by overweight adults, but also by children to support their optimum growth. Intervention of terasi shrimp powder should be implemented step by step from national up to global governance program to face the DBM. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Acetes%20indicus" title="Acetes indicus">Acetes indicus</a>, <a href="https://publications.waset.org/abstracts/search?q=alternative%20food" title=" alternative food"> alternative food</a>, <a href="https://publications.waset.org/abstracts/search?q=double%20burden%20of%20malnutrition" title=" double burden of malnutrition"> double burden of malnutrition</a>, <a href="https://publications.waset.org/abstracts/search?q=sensory%20evaluation" title=" sensory evaluation"> sensory evaluation</a> </p> <a href="https://publications.waset.org/abstracts/54582/diversification-of-indonesian-terasi-shrimp-acetes-indicus-powder-as-alternative-and-sustainable-food-for-the-double-burden-of-malnutrition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54582.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">304</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">113</span> Resistance of Mycobacterium tuberculosis to Daptomycin</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ji-Chan%20Jang">Ji-Chan Jang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Tuberculosis is still major health problem because there is an increase of multidrug-resistant and extensively drug-resistant forms of the disease.

Shrimp samples in fresh condition were collected to perform the microbial assessment and 10 pathogenic isolates for antibiotic sensitivity test to 12 antibiotics. The results show that total bacterial count of all the samples were beyond the acceptable limit 105 cfu/g. In case of total coliform and E. coli density, no substantial difference (p<0.5) was found between the different shrimp samples from different districts and also high quantity of TC exceeding the limit (>102 cfu/g) proves the poor quality of shrimp. The FC abundance found in shrimps of Bagerhat and Satkhira was similar and significantly higher (p<0.5) than that of Khulna samples. No significant difference (p<0.5) was found among the high density of Salmonella-Shigella, Vibrio spp., and Staphylococcus spp. of the shrimp samples from the source places. In case of antibiotic sensitivity patterns, all of them were resistant to ampicillin, Penicillin and sensitive to kanamycin. Most of the isolates were frequently sensitive to ciprofloxacin and streptomycin in the sensitivity test. In case of nutritional composition, no significant difference (t-test, p<0.05) was found among protein, lipid, moisture and ash contents of shrimp samples. The findings prove that shrimp under this study was more or less contaminated and samples from Satkhira were highly privileged with food borne pathogens which confirmed the unhygienic condition of the shrimp farms as well as the presence of antibiotic resistance bacteria in shrimp fish supposed to threat food safety and deteriorate the export quality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=food%20borne%20pathogens" title="food borne pathogens">food borne pathogens</a>, <a href="https://publications.waset.org/abstracts/search?q=satkhira" title=" satkhira"> satkhira</a>, <a href="https://publications.waset.org/abstracts/search?q=penaeus%20indicus" title=" penaeus indicus"> penaeus indicus</a>, <a href="https://publications.waset.org/abstracts/search?q=antibiotic%20sensitivity" title=" antibiotic sensitivity"> antibiotic sensitivity</a>, <a href="https://publications.waset.org/abstracts/search?q=southwest%20Bangladesh" title=" southwest Bangladesh"> southwest Bangladesh</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20safety" title=" food safety"> food safety</a> </p> <a href="https://publications.waset.org/abstracts/2663/microbial-quality-assessment-of-indian-white-shrimp-penaeus-indicus-from-southwest-bangladesh" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2663.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">706</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">111</span> High Throughput LC-MS/MS Studies on Sperm Proteome of Malnad Gidda (Bos Indicus) Cattle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kerekoppa%20Puttaiah%20Bhatta%20Ramesha">Kerekoppa Puttaiah Bhatta Ramesha</a>, <a href="https://publications.waset.org/abstracts/search?q=Uday%20Kannegundla"> Uday Kannegundla</a>, <a href="https://publications.waset.org/abstracts/search?q=Praseeda%20Mol"> Praseeda Mol</a>, <a href="https://publications.waset.org/abstracts/search?q=Lathika%20Gopalakrishnan"> Lathika Gopalakrishnan</a>, <a href="https://publications.waset.org/abstracts/search?q=Jagish%20Kour%20Reen"> Jagish Kour Reen</a>, <a href="https://publications.waset.org/abstracts/search?q=Gourav%20Dey"> Gourav Dey</a>, <a href="https://publications.waset.org/abstracts/search?q=Manish%20Kumar"> Manish Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sakthivel%20Jeyakumar"> Sakthivel Jeyakumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Arumugam%20Kumaresan"> Arumugam Kumaresan</a>, <a href="https://publications.waset.org/abstracts/search?q=Kiran%20Kumar%20M."> Kiran Kumar M.</a>, <a href="https://publications.waset.org/abstracts/search?q=Thottethodi%20Subrahmanya%20Keshava%20Prasad"> Thottethodi Subrahmanya Keshava Prasad </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Spermatozoa are the highly specialized transcriptionally and translationally inactive haploid male gamete. The understanding of proteome of sperm is indispensable to explore the mechanism of sperm motility and fertility. Though there is a large number of human sperm proteomic studies, in-depth proteomic information on Bos indicus spermatozoa is not well established yet. Therefore, we illustrated the profile of sperm proteome in indigenous cattle, Malnad gidda (Bos Indicus), using high-resolution mass spectrometry. In the current study, two semen ejaculates from 3 breeding bulls were collected employing the artificial vaginal method. Using 45% percoll purification, spermatozoa cells were isolated. Protein was extracted using lysis buffer containing 2% Sodium Dodecyl Sulphate (SDS) and protein concentration was estimated. Fifty micrograms of protein from each individual were pooled for further downstream processing. Pooled sample was fractionated using SDS-Poly Acrylamide Gel Electrophoresis, which is followed by in-gel digestion. The peptides were subjected to C18 Stage Tip clean-up and analyzed in Orbitrap Fusion Tribrid mass spectrometer interfaced with Proxeon Easy-nano LC II system (Thermo Scientific, Bremen, Germany). We identified a total of 6773 peptides with 28426 peptide spectral matches, which belonged to 1081 proteins. Gene ontology analysis has been carried out to determine the biological processes, molecular functions and cellular components associated with sperm protein. The biological process chiefly represented our data is an oxidation-reduction process (5%), spermatogenesis (2.5%) and spermatid development (1.4%). The highlighted molecular functions are ATP, and GTP binding (14%) and the prominent cellular components most observed in our data were nuclear membrane (1.5%), acrosomal vesicle (1.4%), and motile cilium (1.3%). Seventeen percent of sperm proteins identified in this study were involved in metabolic pathways. To the best of our knowledge, this data represents the first total sperm proteome from indigenous cattle, Malnad Gidda. We believe that our preliminary findings could provide a strong base for the future understanding of bovine sperm proteomics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bos%20indicus" title="Bos indicus">Bos indicus</a>, <a href="https://publications.waset.org/abstracts/search?q=Malnad%20Gidda" title=" Malnad Gidda"> Malnad Gidda</a>, <a href="https://publications.waset.org/abstracts/search?q=mass%20spectrometry" title=" mass spectrometry"> mass spectrometry</a>, <a href="https://publications.waset.org/abstracts/search?q=spermatozoa" title=" spermatozoa"> spermatozoa</a> </p> <a href="https://publications.waset.org/abstracts/84954/high-throughput-lc-msms-studies-on-sperm-proteome-of-malnad-gidda-bos-indicus-cattle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84954.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">196</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">110</span> Mycobacterium tuberculosis and Molecular Epidemiology: An Overview </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asho%20Ali">Asho Ali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Tuberculosis is a disease of grave concern which infects one-third of the global population.

The mechanism by which Mtb switches from the dormant state to the replicative form is still poorly characterized. Proteome studies have given us an insight into the role of certain proteins in giving stupendous virulence to Mtb, but numerous dotsremain unconnected and unaccounted. The WhiB family of proteins is one such protein that is associated with developmental processes in actinomycetes.Mtb has seven such proteins (WhiB1 to WhiB7).WhiB proteins are transcriptional regulators; their conserved C-terminal HTH motif is involved in DNA binding. They regulate various essential genes of Mtbby binding to their promoter DNA. Biophysical Analysis of the effect of DNA binding on WhiB proteins has not yet been appropriately characterized. Interaction with DNA induces conformational changes in the WhiB proteins, confirmed by steady-state fluorescence and circular dichroism spectroscopy. ITC has deduced thermodynamic parameters and the binding affinity of the interaction. Since these transcription factors are highly unstable in vitro, their stability and solubility were enhanced by the co-expression of molecular chaperones. The present study findings help determine the conditions under which the WhiB proteins interact with their interacting partner and the factors that influence their binding affinity. This is crucial in understanding their role in regulating gene expression in Mtbandin targeting WhiB proteins as a drug target to cure TB. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tuberculosis" title="tuberculosis">tuberculosis</a>, <a href="https://publications.waset.org/abstracts/search?q=WhiB%20proteins" title=" WhiB proteins"> WhiB proteins</a>, <a href="https://publications.waset.org/abstracts/search?q=mycobacterium%20tuberculosis" title=" mycobacterium tuberculosis"> mycobacterium tuberculosis</a>, <a href="https://publications.waset.org/abstracts/search?q=nucleic%20acid%20binding" title=" nucleic acid binding"> nucleic acid binding</a> </p> <a href="https://publications.waset.org/abstracts/157126/functional-characterization-of-transcriptional-regulator-whib-proteins-of-mycobacterium-tuberculosis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157126.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">104</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">108</span> Metagenomic Analysis and Pharmacokinetics of Phage Therapy in the Treatment of Bovine Subclinical Mastitis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vaibhav%20D.%20Bhatt">Vaibhav D.

Around 56 different species including members of Enterobacteriales, Pseudomonadales, Bacillales and Lactobacillales with varying abundance were detected in infected milk. The interesting presence of bacteriophages against Staphylococcus aureus, Escherichia coli, Enterobacter and Yersinia species were observed, especially Enterobacteria and E. coli phages (0∙32%) in Kankrej, Enterobacteria and Staphylococcus phages (1∙05%) in Gir and Staphylococcus phages (2∙32%) in crossbred cattle. NGS findings suggest that phages may be involved in imparting natural resistance of the cattle against pathogens. Further infected milk samples were subjected for bacterial isolation. Fourteen different isolates were identified, and DNA was extracted. Genes (Tet-K, Msr-A, and Mec-A) providing antibiotic resistance to the bacteria were screened by Polymerase Chain Reaction and results were validated with traditional antibiotic assay. Total 3 bacteriophages were isolated from nearby environment of the cattle farm. The efficacy of phages was checked against multi-drug resistant bacteria, identified by PCR. In-vivo study was carried out for phage therapy in mammary glands of female rats “Wister albino”. Mammary glands were infused with MDR isolates for 3 consecutive days. Recovery was observed in infected rats after intramammary infusion of sterile phage suspension. From day 4th onwards, level of C-reactive protein was significant increases up to day 12th . However, significant reduction was observed between days 12th to 18th post treatment. Bacteriophages have significant potential as antibacterial agents and their ability to replicate exponentially within their hosts and their specificity, make them ideal candidates for more sustainable mastitis control. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bacteriophages" title="bacteriophages">bacteriophages</a>, <a href="https://publications.waset.org/abstracts/search?q=c-reactive%20protein" title=" c-reactive protein"> c-reactive protein</a>, <a href="https://publications.waset.org/abstracts/search?q=mastitis" title=" mastitis"> mastitis</a>, <a href="https://publications.waset.org/abstracts/search?q=metagenomic%20analysis" title=" metagenomic analysis"> metagenomic analysis</a> </p> <a href="https://publications.waset.org/abstracts/65533/metagenomic-analysis-and-pharmacokinetics-of-phage-therapy-in-the-treatment-of-bovine-subclinical-mastitis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65533.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">315</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">107</span> Biocompatible Chitosan Nanoparticles as an Efficient Delivery Vehicle for Mycobacterium Tuberculosis Lipids to Induce Potent Cytokines and Antibody Response through Activation of γδ T-Cells in Mice</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ishani%20Das">Ishani Das</a>, <a href="https://publications.waset.org/abstracts/search?q=Avinash%20Padhi"> Avinash Padhi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sitabja%20Mukherjee"> Sitabja Mukherjee</a>, <a href="https://publications.waset.org/abstracts/search?q=Santosh%20Kar"> Santosh Kar</a>, <a href="https://publications.waset.org/abstracts/search?q=Avinash%20Sonawane"> Avinash Sonawane</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Activation of cell mediated and humoral immune responses to Mycobacterium tuberculosis (Mtb) are critical for protection. Herein, we show that mice immunized with Mtb lipid bound chitosan nanoparticles(NPs) induce secretion of prominent Th1 and Th2 cytokines in lymph node and spleen cells, and also induced significantly higher levels of IgG, IgG1, IgG2 and IgM in comparison to control mice measured by ELISA. Furthermore, significantly enhanced γδ-T cell activation was observed in lymph node cells isolated from mice immunized with Mtb lipid coated chitosan-NPs as compared to mice immunized with chitosan-NPs alone or Mtb lipid liposomes through flow cytometric analysis. Also, it was observed that in comparison to CD8+ cells, significantly higher CD4+ cells were present in both the lymph node and spleen cells isolated from mice immunized with Mtb lipid coated chitosan NP. In conclusion, this study represents a promising new strategy for efficient delivery of Mtb lipids using chitosan NPs to trigger enhanced cell mediated and antibody response against Mtb lipids. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antibody%20response" title="antibody response">antibody response</a>, <a href="https://publications.waset.org/abstracts/search?q=chitosan%20nanoparticles" title=" chitosan nanoparticles"> chitosan nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=cytokines" title=" cytokines"> cytokines</a>, <a href="https://publications.waset.org/abstracts/search?q=mycobacterium%20tuberculosis%20lipids" title=" mycobacterium tuberculosis lipids"> mycobacterium tuberculosis lipids</a> </p> <a href="https://publications.waset.org/abstracts/55795/biocompatible-chitosan-nanoparticles-as-an-efficient-delivery-vehicle-for-mycobacterium-tuberculosis-lipids-to-induce-potent-cytokines-and-antibody-response-through-activation-of-ghd-t-cells-in-mice" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55795.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">280</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">106</span> Synthesis and Molecular Docking of Isonicotinohydrazide Derivatives as Anti-Tuberculosis Candidates</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ruswanto%20Ruswanto">Ruswanto Ruswanto</a>, <a href="https://publications.waset.org/abstracts/search?q=Richa%20Mardianingrum"> Richa Mardianingrum</a>, <a href="https://publications.waset.org/abstracts/search?q=Tita%20Nofianti"> Tita Nofianti</a>, <a href="https://publications.waset.org/abstracts/search?q=Nur%20Rahayuningsih"> Nur Rahayuningsih</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Tuberculosis (TB) is a chronic disease as a result of Mycobacterium tuberculosis. It can affect all age groups, and hence, is a global health problem that causes the death of millions of people every year. One of the drugs used in tuberculosis treatment is isonicotinohydrazide. In this study, N'-benzoylisonicotinohydrazide derivative compounds (a-l) were prepared using acylation reactions between isonicotinohydrazide and benzoyl chloride derivatives, through the reflux method. Molecular docking studies suggested that all of the compounds had better interaction with Mycobacterium tuberculosis enoyl-acyl carrier protein reductase (InhA) than isonicotinohydrazide. It can be concluded that N'-benzoylisonicotinohydrazide derivatives (a-l) could be used as anti-tuberculosis candidates. From the docking results revealed that all of the compounds interact well with InhA, with compound g (N'-(3-nitrobenzoyl)isonicotinohydrazide) exhibiting the best interaction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti-tuberculosis" title="anti-tuberculosis ">anti-tuberculosis </a>, <a href="https://publications.waset.org/abstracts/search?q=docking" title=" docking"> docking</a>, <a href="https://publications.waset.org/abstracts/search?q=InhA" title=" InhA"> InhA</a>, <a href="https://publications.waset.org/abstracts/search?q=N%27-benzoylisonicotinohydrazide" title=" N&#039;-benzoylisonicotinohydrazide"> N&#039;-benzoylisonicotinohydrazide</a>, <a href="https://publications.waset.org/abstracts/search?q=synthesis" title=" synthesis"> synthesis</a> </p> <a href="https://publications.waset.org/abstracts/91333/synthesis-and-molecular-docking-of-isonicotinohydrazide-derivatives-as-anti-tuberculosis-candidates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91333.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">310</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">105</span> Investigation of Rifampicin and Isoniazid Resistance Mutated Genes in Mycobacterium Tuberculosis Isolated From Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyyed%20Mohammad%20Amin%20Mousavi%20Sagharchi">Seyyed Mohammad Amin Mousavi Sagharchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Mahmoudi%20Nasab"> Alireza Mahmoudi Nasab</a>, <a href="https://publications.waset.org/abstracts/search?q=Tim%20Bakker"> Tim Bakker</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Mycobacterium tuberculosis (MTB) is the most intelligent bacterium that existed in the world to our best knowledge. This bacterium can cause tuberculosis (TB) which is responsible for its spread speed and murder of millions of people around the world. MTB has the practical function to escape from anti-tuberculosis drugs (AT), for this purpose, it handles some mutations in the main genes and creates new patterns for inhibited genes. Method and materials: Researchers have their best tries to safely isolate MTB from the sputum specimens of 35 patients in some hospitals in the Tehran province and detect MTB by culture on Löwenstein-Jensen (LJ) medium and microscopic examination. DNA was extracted from the established bacterial colony by enzymatic extraction method. It was amplified by the polymerase chain reaction (PCR) method, reverse hybridization, and evaluation for detection of resistance genes; generally, researchers apply GenoType MTBDRplus assay. Results: Investigations of results declare us that 21 of the isolated specimens (about 60%) have mutation in rpoB gene, which resisted to rifampicin (most prevalence), and 8 of them (about 22.8%) have mutation in katG or inhA genes which resisted to isoniazid. Also, 4 of them (about 11.4%) don't have any mutation, and 2 of them (about 5.7%) have mutation in every three genes, which makes them resistant to the two drugs mentioned above. Conclusion: Rifampicin and isoniazid are two essential AT that using in the first line of treatment. Resistance in rpoB, and katG, and inhA genes related to mentioned drugs lead to ineffective treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mycobacterium%20tuberculosis" title="mycobacterium tuberculosis">mycobacterium tuberculosis</a>, <a href="https://publications.waset.org/abstracts/search?q=tuberculosis" title=" tuberculosis"> tuberculosis</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=isoniazid" title=" isoniazid"> isoniazid</a>, <a href="https://publications.waset.org/abstracts/search?q=rifampicin" title=" rifampicin"> rifampicin</a> </p> <a href="https://publications.waset.org/abstracts/165030/investigation-of-rifampicin-and-isoniazid-resistance-mutated-genes-in-mycobacterium-tuberculosis-isolated-from-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165030.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">96</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">104</span> The Role of Immunologic Diamonds in Dealing with Mycobacterium Tuberculosis; Responses of Immune Cells in Affliction to the Respiratory Tuberculosis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyyed%20Mohammad%20Amin%20Mousavi%20Sagharchi">Seyyed Mohammad Amin Mousavi Sagharchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Elham%20Javanroudi"> Elham Javanroudi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Tuberculosis (TB) is a known disease with hidden features caused by Mycobacterium tuberculosis (MTB). This disease, which is one of the 10 deadliest in the world, has caused millions of deaths in recent decades. Furthermore, TB is responsible for infecting about 30% population of world. Like any infection, TB can activate the immune system by locating and colonization in the human body, especially in the alveoli. TB is granulomatosis, so MTB can absorb the host’s immune cells and other cells to form granuloma. Method: Different databases (e.g., PubMed) were recruited to prepare this paper and fulfill our goals to search and find effective papers and investigations. Results: Immune response to MTB is related to T cell killers and contains CD1, CD4, and CD8 T lymphocytes. CD1 lymphocytes can recognize glycolipids, which highly exist in the Mycobacterial fatty cell wall. CD4 lymphocytes and macrophages form granuloma, and it is the main line of immune response to Mycobacteria. On the other hand, CD8 cells have cytolytic function for directly killing MTB by secretion of granulysin. Other functions and secretion to the deal are interleukin-12 (IL-12) by induction of expression interferon-γ (INF-γ) for macrophages activation and creating a granuloma, and tumor necrosis factor (TNF) by promoting macrophage phagolysosomal fusion. Conclusion: Immune cells in battle with MTB are macrophages, dendritic cells (DCs), neutrophils, and natural killer (NK) cells. These immune cells can recognize the Mycobacterium by various receptors, including Toll-like receptors (TLRs), Nod-like receptors (NLRs), and C-type lectin receptors (CLRs) located in the cell surface. In human alveoli exist about 50 dendritic macrophages, which have close communication with other immune cells in the circulating system and epithelial cells to deal with Mycobacteria. Against immune cells, MTB handles some factors (e.g., cordfactor, O-Ag, lipoarabinomannan, sulfatides, and adenylate cyclase) and practical functions (e.g., inhibition of macrophages). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mycobacterium%20tuberculosis" title="mycobacterium tuberculosis">mycobacterium tuberculosis</a>, <a href="https://publications.waset.org/abstracts/search?q=immune%20responses" title=" immune responses"> immune responses</a>, <a href="https://publications.waset.org/abstracts/search?q=immunological%20mechanisms" title=" immunological mechanisms"> immunological mechanisms</a>, <a href="https://publications.waset.org/abstracts/search?q=respiratory%20tuberculosis" title=" respiratory tuberculosis"> respiratory tuberculosis</a> </p> <a href="https://publications.waset.org/abstracts/165031/the-role-of-immunologic-diamonds-in-dealing-with-mycobacterium-tuberculosis-responses-of-immune-cells-in-affliction-to-the-respiratory-tuberculosis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165031.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">109</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">103</span> Docking and Dynamic Molecular Study of Isoniazid Derivatives as Anti-Tuberculosis Drug Candidate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Richa%20Mardianingrum">Richa Mardianingrum</a>, <a href="https://publications.waset.org/abstracts/search?q=Srie%20R.%20N.%20Endah"> Srie R.
