Experimental intrauterine inoculation of pregnant ewes with ureaplasmas



Experimental intrauterine inoculation of pregnant ewes with ureaplasmas



Veterinary Research Communications 9(1): 35-44



The pregnancies of 13 ewes which were inoculated intrauterine with one of 2 strains of ovine ureaplasmas resulted in 9 normal and 3 abnormal births, and one ewe was found to be no longer pregnant on postmortem examination. Vaginal ureaplasma infection was detected in the majority of ewes only after lambing. Of the 12 ewes examined at postmortem, ureaplasmas were isolated from the uterus of 5 out of the 6 necropsied up to 21 days post-partum. The vulvar/preputial areas of the majority of lambs that survived were infected with ureaplasmas for the duration of the experiment, but infections of the nasal cavity and eye areas, detected at birth in 4 lambs, were resolved within 8 days postpartum. The only pathological effects detected that could possibly be attributed to ureaplasma infection were a placentitis in an ewe that aborted, and the resorption of the fetus in another.
