Evaluation of the occurrence of Salmonella serovars and its Antibiotic Susceptibility in Apparently Healthy domestic animals in rural areas of East Azerbaijan province

Background and Aim: Salmonellosis is one of the more common zoonotic diseases that cause diarrhea and systemic infections. Today, antimicrobial resistances are one of the major health problems in human and veterinary medicine which are more in rural areas. The aim of this study was investigation of presence and antimicrobial resistance profile of Salmonella species in domestic animals which were herd in rural areas (East Azerbaijan province). Material and Methods: In this study a total number of ۲۵۰ samples were obtained from domestic ruminant (Including ۱۰۰ cows, ۵۰ sheep, ۵۰ goat and ۵۰ buffalo) in rural areas. The feces and rectal swab specimens cultured in enrichment and selective media and isolates were characterized by biochemical test and stereotyped by O and H antisera. Salmonella isolates were tested for sensitivities to routine antibiotic by method of Kirby-Bauer disc diffusion method. Results and Conclusions: Out of two hundred and fifty samples tested, ۱۵ (۶%) were identified as Salmonella strains including S. dublin (۷ cases), S. typhimurium (۵ cases) and S. enteritidis (۳ cases). Many isolates proved multi antibiotic resistance (MAR). In overall, isolating multiple antibiotic resistance Salmonella species at high rates showed apparently healthy ruminant might act as reservoirs and could pose an important public health threat.
