Abstract
The present studies were done to determine the presence of Yersinia entero-colitica in dogs. During 13 months from August 1974 to August 1975, the contents of theileum, cecum, colon and rectum, and the mesenteric Nymph nodes of 451 dogs in Sapporowere examined. Three hundred and ninety-five strains of Yersinia enterocolitica were iso-lated from 25 out of 451 dogs examined. Two hundred and eighty-two strains from 16dogs were determined as 0 group (0) 3, biovar 4; 60 strains from 5 dogs 05B, biovar 2:47 strains from 2 dogs 09, biovar 2; 4 strains from 1 dog 06, biovar 1; and 2 strains from2 dogs 05A, biovar 1. O group of strains isolated from 1 dog was the same in 24 of the25 dogs. From the other I dog, however, the strains of both 03 and 09 were isolated atthe same time. The isolation of 09 strains from dogs is the first in Japan. The strainsof 03 or 09, which are known to be pathogenic agents in man, were isolated in 17 dogs, and many of them, from the contents of ileum, cecum, colon and rectum in 9 dogs. Onthe basis of these results, the significance of the presence of Yer.sinia enterocoZitica in dogswas discussed.
