SURVEY ON SALMONELLA CONTAMIATION OF WILD RODENTS IN MAZANDARAN PROVINCE

Background and Aim:Salmonella is a pathogen of worldwide importance, causing disease in a vast range of hosts including humans. Salmonella infection can cause severe disease in animals, which is sometimes associated with high mortality. Salmonella has repeatedly been isolated from wild mice and rats, which represent important reservoir hosts on farms and in food production. Environmental conditions can influence Salmonella spp survival. The study was conducted to determine the frequency of salmonella contamination in the fecal samples of rodents trapped across the different villages and cities in Mazandaran Province.Methods:A total of 90 Mus musculuses were trapped and their rectal swabs were used for detection of salmonella by conventional microbial culture method. Positive samples were serotyped.Results:Salmonella spp were detected in 20 fecal samples containing 11 S. typhymurium and 9 S. enteritiddis. There was no difference between male and female ones in salmonella contamination.Conclusion:Salmonella contamination of trapped Mus musculuses, indicating a potential risk associated with these animals as sampled Mus musculuses originated from locations near the villages. It is therefore imperative that regular rodent control measures should be practiced to reduce risk of salmonella contamination in contaminated areas
