Yersinia enterocolitica associated with third trimester abortion in buffaloes

A group of buffaloes aborted at the third trimester of their gestational period. Yersinia enterocolitica was isolated from all cases. All aborted animal sera had high antibody titres against Y. enterocolitica antigen which crossreacted significantly with Brucella abortus antigen. All animals were culturally negative after intrauterine infusion of gentamycin sulphate (160 mg/day) for three consecutive days.
