Salmonellosis is a very important infectious disease of animal species including the calves. Economic losses due to disease can be considerable. It is also one of the most important zoonotic diseases and it can be public health threatening for human. In this study, the prevalence and clinical features of Salmonellosis in 420 calves in 18 dairy farms of Kermanshah province have been evaluated. During a period of 1 year and in each season, fecal samples from calves with diarrhea (in priority) and other calves not clinically in good condition were taken and examined. The Vital status and clinical symptoms of all calves were also recorded. Samples were transported to the microbiology laboratory of the faculty of veterinary medicine of Razi University in enriched media and complete microbiological tests have been performed on them. Out of the 420 samples, only 2 cases (0.47 percent) were positive for Salmonella. Due to early detection and appropriate treatment, both cases went healthy very soon. The age of these calves that were detected in winter was around 1.5 month. Other isolated bacteria were included: E.coli in 348 cases, Proteus in 204 cases, Citrobacter in 106 cases, Yersinia in 60 cases and Enterobacter in 48 cases.
