The increased prevalence of Salmonella contamination in poultry has gained considerablescientific attention during the last few decades. Poultry is one of the most common reservoirs ofSalmonella and contamination of poultry products can occur during the different stages of poultryproduction. The purpose of the study was to determine the prevalence of antibiotic resistantSalmonella in poultry and poultry products in Mauritius. Thirty poultry samples were analyzed forSalmonella using traditional culturing, serological and PCR assays. The isolates were then testedfor resistance against five antibiotics (ampicillin, chloramphenicol, erythromycin, streptomycinand tetracycline) using the disc diffusion susceptibility test. Serotyping showed positiveagglutination for Salmonella using polyvalent Anti-O and Anti-H antisera. Out of the 30 samplestested, only 5 samples were confirmed as Salmonella. It was found that 72% of isolates wereresistant to at least one antibiotic. The frequency of antibiotic resistance ranked in the followingorder: tetracycline (100%), erythromycin (80%), streptomycin (80%), chloramphenicol (60%)respectively. However, 2 out of 5 isolates were susceptible to ampicillin. The findings of thisstudy strongly indicated that antibiotic resistance patterns of Salmonella spp. observed in thisstudy are comparable to patterns of other countries
