title: Brucella ovis infection in two flocks of sheep.
abstract: Brucella ovis infection could not be eradicated from two flocks of sheep despite serologically testing and culling the infected rams for four years. The hypothesis that the ewes played a major role in the maintenance of the infection in both flocks was investigated by using serological, bacteriological and pathological criteria. Specific antibodies against B ovis were demonstrated in 71 ewes in the two flocks. Forty-four of the seropositive ewes were slaughtered for bacteriological and pathological studies and B ovis was isolated from 16 of them; the uterus was the target organ of the infection, although extrauterine infection was also demonstrated in some of the infected ewes.
