چکیده
Background and Aim : one of important problems that can be transmitted by contaminated foodto human is food infection, this transmission can sometimes lead to the contamination of manypeople who have fed from the same source.Methods : all the samples that were sent to the food microbiology research center during one yearwere microbiologically examined. After biochemical investigations, Salmonella spp isolates wereanalyzed by the presence of the invA gene. This gene is considered as one of the important genesin coding the secretory system of Salmonella, whose product is ۱۰۱۰ kilobases. The drug resistanceof these isolates investigated through Kirby-bauer disk diffusion method. Imipenem, ceftriaxoneand trimethoprim-sulfamethoxazole antibiotic were investigated.Results : ۴۰ isolates contained the invA gene, which indicate the presence of Salmonella spp infood outbreak samples. In relation to the trimethoprim-sulfamethoxazole, the level of resistance islower than the other antibiotic, and a number of isolates shown intermediate resistance to thisantibiotic.Conclusion : Despite the development of health protocols and adherence to health guidelines, itis still observed that bacterial diseases can cause food outbreaks as in the past. Considering thatcoliform bacteria were also present in the majority of the samples, it is a sign of oral-fecaltransmission, so it is suggested to reduce food outbreaks by monitoring the preparation oftraditional food and also by training the people who prepare the food. In this study, it wasdetermining that the antibiotic trimethoprim-sulfamethoxazole can be the suitable drug fortreatment.کلیدواژه ها
