   "abstract": "Abortions, accompanied by placental retention and weight loss, occurred during February and March in 19% of 120 and 10% of 108 beef cows and heifers on two neighboring ranches in southern Saskatchewan. A diagnosis of Campylobacter jejuni abortion was made based on lesions of necrotizing and suppurative placentitis and fetal bronchopneumonia in association with the culture of large numbers of C. jejuni from placentas and fetal tissues. Campylobacter jejuni was isolated with variable frequency from fecal samples of aborting and healthy cows, and scouring and healthy calves. Campylobacter jejuni serotype 2 (Lior) was isolated from fetal tissues and feces of a scouring calf, whereas C. jejuni serotypes 1, 4, 5 and 99 were isolated from feces of in-contact cattle. We hypothesized that the source and mode of transmission of C. jejuni was fecal contamination of water supplies and feeding grounds by carrier cows or wildlife.",
