Recently, an increasing number of multi drug resistant Salmonella species have been emerged due to overuse of antibiotics in veterinary and human medicine which has adverse consequences on public health. The present study was conducted with the aim of investigating the prevalence of Salmonella infection in village chickens in Sistan region and determining the prevalence of the antibiotic resistance genes in Salmonella isolated from these birds. In this study, 100 chickens were randomly selected from five counties of Sistan region. A cloacal swab sample was taken from each bird and also information about age, gender, breed, proximity with other birds, proximity with waterfowl, proximity with livestock, and receiving different antibiotics especially tetracycline were obtained using a questionnaire. Conventional culture methods used for Salmonella detection and isolation. Then, amplification of invA gene by PCR was used to confirm Salmonella colonies. Finally, 27 samples were confirmed to be infected with Salmonella by both culture and PCR methods. Disk diffusion method was used to determine the sensitivity to 4 antibiotics including; tetracycline, gentamicin, cefepime, and difloxacin. The results of the present study showed that proximity to waterfowl (OR = 0.273) significantly mitigates the risk of Salmonella infection. For the isolates, the highest resistance was recorded against cefepime and the highest susceptibility was to difloxacin. The presence proportion of tetA and tetB in tetracycline resistant isolates was higher than that in susceptible ones but this difference was not statistically significant.
