[Abortions in cows caused by Corynebacterium pyogenes].
Bacteriologic investigations of embryos, fetuses, and placentae of cows that had miscarried, uterine and milk samples taken from animals with endometritis and mastitis, and bull semen samples revealed the presence of Corynebacterium pyogenes. It was established that this organism ranks first in the group of occasionally pathogenic microflora that was associated with the occurrence of abortions in cows. It was isolated from in 9.2 per cent of the cases from fetuses, 5.3 per cent of the cases from embryos, and 8.1 per cent of the cases from placentae. On farms with records of Corynebacterium pyogenes abortions all endometritis and mastitis cases could be associated with the same infection. The organisms was demonstrated in the uterine secretion in both clinically normal cows and bull semen. Corynebacterium pyogenes was found to be viable for a long time, and, therefore, represented a serious source of infection--abortions, endometritis, and mastitis.
