Abstract
During a 2 yr period, March 1977-April 1979, 92 bovine abortions were studied. The cause of abortion was determined in 34.8% of the cases examined. Opportunistic bacteria, the most commonly diagnosed cause of abortion, accounted for 31.2% of the cases. Leptospirosis was associated with 28.1% of the abortions, infectious bovine rhinotracheitis and fungi in 15.7% and bovine viral diarrhea in 6.2%. A congenital abnormality accounted for 1 case (3.1%). In 23 cases (25%), there was no definitive diagnosis, in spite of evidence of pathogen or suggestive findings of pathology. No findings were recorded in 35.8% of the (possibly noninfectious) cases; in 4 cases (4.4%) specimens were unsatisfactory for examination.
