Abstract: The role of Y. enterocolitica in enteric diseases for cattle, sheep and goats was studied, Y enterocolitica was isolated 8% from buffaloes, 2% from cows,. 1.5% from sheep and goats each. The isolated 24 isolates were related to sero/ biovar 0:3/2 and 2 were related to sero/biovar 0:9/1.Y.enterocolitica 0:3 was the most predominant in different animal species. The isolated Y, enterocolitica were tested to heat stable enterotoxin, guinea pig conjunctivitis and Congo red tests, Y. enterocolitica was experimentally infected in mice and it was found that the percentage of illness and deaths were increased with the increase of the dose of the given micro-organisms. The symptoms were emaciation. weakness and diarrhea, Postmortem lesions were enlargement or stomach. swelling or small intestine.
pneumonia. liver necrosis. congestion and enlargement of spleen and urinary tract affection.Y. enterocolitica was exprimentally injected in goats, vaccination of goat with killed vaccine gave good level of protection against Y. enterocolitica infection, Serological tests revealed obvious cross reaction between B. abortus and Y. enterocolitica 0:9 . Antibiogram of isolated y. enterocolitica revealed no variation between Y. enterocolitica 0:3 and 0:9 in sensitivity to the used antimicrobial agents. The isolated strains were sensitive to all antimicrobial agents used in this study. except ampeillin was resistance and Nalidix acid was moderate in sensitivity in vitro to Y. enterocolitica .
