Abstract
Yersinia enterocolitica and Yersinia pseudotuberculosis were isolated from 83 (20.4%) out of 406 rodents and from 64 (8.8%) out of 725 cat feces samples. The isolates from rodents include 59 Y. enterocolitica and 24 Y. pseudotuberculosis, whereas, the isolates from cat feces include 19 Y. enterocolitica and 45 Y. pseudotuberculosis. The rates of virulent Y. enterocolitica and Y. pseudotuberculosis in rodent isolates were found to be 10.2% and 79.2% respectively, whereas, for cat fecal isolates these rates were 42.1% and 86.7%, respectively. The highest incidence of the two species in both cat feces and rodents occurred in the cold months.
