OBJECTIVE: Salmonella spp. are one of the leading foodborne pathogens worldwide naturally found in the intestines of many animals. People that are in direct contact with the infected animals or their cages may become ill. The aim of this study was to determine the prevalence, antibiogram and virulence genes associated with Salmonella serovars from fecal samples of animals intended for consumption in Southern Benin. RESULTS: Out of a total of 406 samples, 2.46% were positive. The isolates identified were multidrug-resistant Salmonella spp. to penicillins, first generation cephalosporins and some aminoglycosides. All Salmonella isolates produced invA gene of 284 bp, fimA of 85 bp and stn of 260 bp. The spvC gene (571 bp) was present in 10% of the isolates whereas the spvR gene (310 bp) was found in 20% of the isolates. The control strain possessed all the tested genes. The invA gene implies that strains are able to invade epithelial cells. The fimA and stn genes present in all isolates show that they are capable of causing gastrointestinal illness in humans. The presence of spvC and spvR genes suggests the possibility of these strains to produce toxins.
