[Epizootiological evaluation of the peroral and vaginal infection of sheep with S. abortus ovis].

Epizootiologic evaluation is made of the oral and the vaginal Salmonella abortus ovis infection in sheep in view of the occurrence and persistence of the infection within the sheep flocks. It has been established that the presence of carriers of infection depends on the physiologic status of the animals at the time of contracting the infection. Abortion, lambing, and the setting in of estrus were shown to affect favourably the existing carrier status. Salmonella abortus ovis organisms were most commonly isolated from the uterus, ovaries, mesenterial lymph nodes, and the duodenum.
