| 英文描述 | Sporadic abortions in cattle can occur due to many different bacteria; ACTINOMYCES PYOGENES, LISTERIA MONOCYTOGENES, CAMPYLOBACTER FETUS var. FETUS, BACILLUS spp., HEMOPHILUS SOMNUS, ACTINOBACILLUS, PASTEURELLA, and ESCHERICHIA COLI are most common. ACTINOMYCES PYOGENES in sheep and goats and ACTINOBACILLUS SEMINIS and HISTOPHILUS OVIS in sheep are sporadicaly isolated. An anerobic slightly curved, taperd, currogated, rod-shaped bacterium was isolated from the livers of aborted lambs, and abortions were experimentally reproduced with this organism. Other anaerobic bacteria are occasionally isolated from ruminant fetuses. |
