BACKGROUND: Salmonella spp. are zoonotic pathogens that infect a wide range of domestic and wild animals. Opportunistic wild carnivores such as Golden jackal (Canis aureus) which stray in high numbers around the rural areas can act as potential sources of salmonella spp in humans and wild & domestic animals in northern Iran. OBJECTIVES: The object of this survey was to examine the Salmonella spp infection including the antibiotic-resistant pattern in golden jackals in Golestan and Mazandaran Province. METHODS: Between 2013 and 2015, fecal samples of 50 road-killed Golden jackals (Canis aureus), were collected and analyzed for Salmonella contamination by classical microbiological culture methods and PCR followed by serotyping and determining of antibiotic resistant pattern. RESULTS: Five isolated salmonella belonging to 2 serotypes: S typhymurium (3/5) and S arizona (2/5) were isolated by culturing and PCR. The rate of salmonella contamination was similar between females and males and higher incidence was detected in jackals under 2 years old. CONCLUSIONS: 10% Salmonella infection of sampled golden jackals highlights the neglected role of this species in zoonotic diseases dissemination and poses a great threat to human health in rural areas of Golestan and Mazandaran Provinces. The epidemiological study on role of wild animals in the spread of salmonella and developing strategy for salmonellosis prevention and control seems necessary.
