Abstract: Samples from 350 routine deer cases submitted to Invermay Animal Health Laboratory for diagnosis during 1979-1982 were examined specifically for the presence of Yersinia sp. An analysis of 57 cases of yersiniosis due to Yersinia pseudotuberculosis is made and two cases due to Yeminia enterocolitica are described. The occurrence of cases appeared strongly correlated with periods of stress, predominantly in winter when cool wet conditions and lack of grazing combined to precipitate the disease. Animals up to one year old were most commonly affected (64% of cases). Of the 61 strains of Yersinia pseudotuberculosis isolated 35 were of Serotype I, 17 of Serotype II and nine of Serotype III. All strains of Yersinia pseudotuberculosis and the strains of Yersinia enterocolitica isolated from the two cases described were Hela cell invasive and gave a positive autoagglutination test for virulence.
