This study determined the diversity and antibiotic resistance gene profile of <jats:italic>Salmonella enterica<\/jats:italic> serovars isolated from humans and food animals. Using standard methods, <jats:italic>Salmonella<\/jats:italic> spp. were isolated from fecal samples, profiled for antimicrobial susceptibility and resistance genes. Seventy-one <jats:italic>Salmonella<\/jats:italic> isolates were recovered from both humans and food animals comprising cattle, sheep, and chicken. Forty-four serovars were identified, with dominant <jats:italic>Salmonella<\/jats:italic> Budapest (31.8%). Rare serovars were present in chicken (<jats:italic>S<\/jats:italic>. Alfort, <jats:italic>S<\/jats:italic>. Wichita, <jats:italic>S<\/jats:italic>. Linton, <jats:italic>S<\/jats:italic>. Ealing, and <jats:italic>S<\/jats:italic>. Ebrie) and humans (<jats:italic>S<\/jats:italic>. Mowanjum, <jats:italic>S<\/jats:italic>. Huettwillen, <jats:italic>S<\/jats:italic>. Limete, and <jats:italic>S<\/jats:italic>. Chagoua). Sixty-eight percent of isolates were sensitive to all test antibiotics, while the highest rate of resistance was to nalidixic acid (16.9%; <jats:italic>n<\/jats:italic>\u2009=\u200912), followed by ciprofloxacin (11.3%; <jats:italic>n<\/jats:italic>\u2009=\u20098) and tetracycline (9.9%; <jats:italic>n<\/jats:italic>\u2009=\u20098). Five isolates (7%) were multidrug-resistant and antimicrobial resistance genes coding resistance to tetracycline (<jats:italic>tetA<\/jats:italic>), beta-lactam (<jats:italic>bla<jats:sub>TEM<\/jats:sub><\/jats:italic>), and quinolone\/fluoroquinolone (<jats:italic>qnrB<\/jats:italic> and <jats:italic>qnrS<\/jats:italic>) were detected. Evolutionary analysis of <jats:italic>gyrA<\/jats:italic> gene sequences of human and food animal <jats:italic>Salmonella<\/jats:italic> isolates revealed variations but are evolutionarily interconnected. Isolates were grouped into four clades with <jats:italic>S<\/jats:italic>. Budapest isolate from cattle clustering with <jats:italic>S<\/jats:italic>. Budapest isolated from chicken, whereas <jats:italic>S<\/jats:italic>. Essen isolated from sheep and chicken was grouped into a clade. Diverse <jats:italic>S. enterica<\/jats:italic> serovars with high antibiotic resistance profile are ubiquitous in food animals; hence, there is a need for surveillance and prudent use of antibiotics in human and veterinary medicine.<\/jats:p>","DOI":"10.1556\/030.66.2019.034","type":"journal-article","created":{"date-parts":[[2019,10,29]],"date-time":"2019-10-29T08:55:51Z","timestamp":1572339351000},"page":"509-527","update-policy":"https:\/\/doi.org\/10.1556\/policypage.crossmark.crossref.1","source":"Crossref","is-referenced-by-count":11,"title":["Molecular
