Nevertheless, its epidemiological effects and multidrug resistance remain poorly studied in the study area. <b>Methods:</b> A cross-sectional study was conducted from March to August 2022 to determine the occurrence, risk factors, and antibiotic susceptibility patterns of <i>Salmonella</i> isolates in the study dairy farms. A total of 232 samples (200 study animals and 32 bulk tank milk) were collected from purposively selected dairy farms in the study area. Again, fecal and bulk tank milk samples were collected, pre-enriched, and cultured to examine the presence of <i>Salmonella</i> following standard techniques. The pure 30 isolates were also subjected to a Kirby-Bauer disk diffusion test on Muller-Hinton agar to assess their antibiotic susceptibility patterns. Binary logistic regression analysis in Statistical Package for Social Sciences (SPSS) Version 25 was used to determine the strength of the risk factors associated with the occurrence of this disease. <b>Findings:</b> The overall prevalence of <i>Salmonella</i> isolates was 12.9% (30/232) across all samples. Among these, 11.5% (23/200) of the fecal samples from the study animals and 21.9% (7/32) of the bulk tank milk samples tested positive for this disease. A statistically significant association was observed between the presence of the <i>Salmonella</i> isolates and the age of the study animals, farm size, bedding, and udder washing practices. The isolates also showed the highest resistance to ampicillin (100%) and tetracycline (96.7%). Conversely, the isolates were most sensitive to ciprofloxacin (100%) and kanamycin (90%). <b>Conclusions:</b> Generally, the high presence of <i>Salmonella</i> isolates and its resistance to drugs pose significant economic and public health challenges.

However, there is limited information about these issues in various parts of the country, particularly in the Amhara Region. Therefore, this study was aimed at determining the prevalence of Hepatitis B virus (HBV), Hepatitis C virus (HCV), and HIV infections and identifies the associated risk factors among pregnant women attending an antenatal care (ANC) unit at Simada Hospital, Amhara Region, Northwest Ethiopia.

The study was aimed at isolating, identifying, and molecularly characterizing bacteria that produce protease enzymes that are highly capable of dehairing goat hide. Several attempts were made to isolate and identify protease-producing bacterial strains from different soil samples of tannery wastes. Initially, a total of four isolates were selected from tannery soil. After the different phenotypic and morphological characterization, one isolate (BS2) showed Gram-positive, rod-shaped, and spore-forming characteristics and could produce novel hair-degrading protease enzymes. The growth profile and protease activity of the bacteria at 37°C were observed; a basal level of extracellular protease increased with time. The enzyme's proteolytic activity was measured, and the unit of enzyme activity of the enzyme sample was 18.1.

This paper provides a systematic review of the relevant publications and conference papers based on the subject of vitiligo diagnosis and confirmation through computer-aided machine learning (ML) techniques. <b>Materials and Methods:</b> A search was conducted using a predetermined set of keywords across three databases, namely, Science Direct, PubMed, and IEEE Xplore. The selection process involved the application of eligibility criteria, which led to the inclusion of research published in reputable journals and conference proceedings up until June 2024. These selected papers were then subjected to full-text screening for additional analysis. Research publications that involved application of ML techniques with targeted population of vitiligo were selected for further systematic review. <b>Results:</b> Ten selected and screened studies are included in this systematic review after applying eligibility criteria along with inclusion and exclusion criteria applied on initial search result which was 244 studies based on vitiligo. Priority is given to those studies only which use ML techniques to perform detection and diagnosis on vitiligo-targeted population. Data analysis was carried out only from the selected and screened research articles that were published in authentic journals and conference proceedings. <b>Conclusion:</b> The importance of applying ML techniques in the clinical diagnosis of vitiligo can give more accurate results and at the same also eliminate the need of biased human judgement. Based on a comprehensive examination of the research, encompassing the methodologies employed and the metrics utilized to assess outcomes, it was determined that there is a need for further research and investigation regarding the application of ML algorithm for the detection and diagnosis of vitiligo with different datasets and more feature extraction.</p>","PeriodicalId":9007,"journal":{"name":"BioMed Research International","volume":"2024 ","pages":"3277546"},"PeriodicalIF":2.6,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11671642/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142902585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
