Bacterial identification and antimicrobial susceptibility testing were performed using established protocols. Data were analysed using descriptive statistics and Pearson\u2019s chi-squared test at\u00a0P\u00a0\u2264 0.05 significance level.Results:\u00a0The overall prevalence of\u00a0Salmonella\u00a0was 21.4%. There were statistically significant associations between\u00a0Salmonella\u00a0prevalence and the farm location (p\u00a0= 0.003), age of chickens (p\u00a0 0.001), and health status of chickens (p\u00a0 0.001). All\u00a0Salmonella\u00a0isolates (n\u00a0= 77; 100.0%) were resistant to cefuroxime. The isolates were also highly resistant to cotrimoxazole (n\u00a0= 74; 96.1%), chloramphenicol (n\u00a0= 73; 94.8%), meropenem (n\u00a0= 72; 93.5%), gentamicin (n\u00a0= 69; 89.6%), and tetracycline (n\u00a0= 64; 83.1%).Conclusion:\u00a0The presence of drug-resistant\u00a0Salmonella\u00a0in commercial layer chickens in Ibadan is a potential threat to consumer health as it increases the risk of carcass contamination and pathogen propagation, and limits the options to control and treat infections in humans and animals. Well-integrated national surveillance systems for monitoring\u00a0Salmonella\u00a0and antimicrobial resistance in poultry are critical.\u00a0<\/jats:p>","DOI":"10.4102\/ajlm.v11i1.1606","type":"journal-article","created":{"date-parts":[[2022,7,14]],"date-time":"2022-07-14T13:28:55Z","timestamp":1657805335000},"source":"Crossref","is-referenced-by-count":8,"title":["Occurrence and antimicrobial susceptibility patterns of Salmonella species from poultry farms in Ibadan, Nigeria"],"prefix":"10.4102","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9967-0722","authenticated-orcid":false,"given":"Terese G.","family":"Orum","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1083-619X","authenticated-orcid":false,"given":"Olayinka O.","family":"Ishola","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4207-7423","authenticated-orcid":false,"given":"Oluwawemimo O.","family":"Adebowale","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2580","published-online":{"date-parts":[[2022,7,20]]},"reference":[{"key":"ref0001","doi-asserted-by":"publisher","DOI":"10.3390\/foods9060776"},{"key":"ref0002","doi-asserted-by":"publisher","DOI":"10.1016\/j.yapd.2015.04.005"},{"key":"ref0003","doi-asserted-by":"publisher","DOI":"10.1128\/CMR.00002-15"},{"key":"ref0004","first-page":"4674235","volume":"13","author":"Abebe","year":"2020","journal-title":"J Trop Med"},{"key":"ref0005","doi-asserted-by":"publisher","DOI":"10.14202\/vetworld.2019.504-521"},{"key":"ref0006","doi-asserted-by":"publisher","DOI":"10.1007\/s10096-016-2760-3"},{"key":"ref0007","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(11)61752-2"},{"key":"ref0008","doi-asserted-by":"publisher","DOI":"10.5897\/AJMR12.2253"},{"key":"ref0009","doi-asserted-by":"publisher","DOI":"10.1002\/mbo3.1067"},{"issue":"14","key":"ref0010","first-page":"180","volume":"5","author":"Odine","year":"2015","journal-title":"J Biol Agric Healthcare"},{"key":"ref0011","doi-asserted-by":"publisher","DOI":"10.1080\/09709274.2005.11905804"},{"issue":"9","key":"ref0012","first-page":"796","volume":"4","author":"Agbaje","year":"2010","journal-title":"Afr J Microbiol Res"},{"key":"ref0013","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0173097"},{"key":"ref0014","doi-asserted-by":"publisher","DOI":"10.1016\/j.vetmic.2009.07.009"},{"key":"ref0015","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0238190"},{"key":"ref0016","doi-asserted-by":"publisher","DOI":"10.2527\/jas.2007-0464"},{"key":"ref0017","doi-asserted-by":"publisher","DOI":"10.1016\/j.tips.2010.08.002"},{"key":"ref0018","doi-asserted-by":"publisher","DOI":"10.9734\/BMRJ\/2014\/5872"},{"key":"ref0019","author":"Thrusfield","year":"2007","journal-title":"Veterinary epidemiology"},{"key":"ref0020","first-page":"1","author":"International Standard Organization","year":"2017","journal-title":"ISO 6579-1:2017: Microbiology of the food chain \u2013 Horizontal method for the detection, enumeration and serotyping of Salmonella \u2013 Part 1: Detection of Salmonella spp"},{"key":"ref0021","doi-asserted-by":"publisher","DOI":"10.1093\/ajcp\/45.4_ts.493"},{"key":"ref0022","author":"Clinical and Laboratory Standards Institute","year":"2018","journal-title":"CLSI Guidelines.
