Twenty-nine cows from a 240-cow drylot Holstein dairy in north-central New Mexico aborted over a period of approximately 5 months. Nine aborted fetuses were necropsied, and all but 1 of the fetuses were between 5 and 7 months of gestation. Microscopic examination of fetal tissues revealed focal necrotizing encephalitis and nonsuppurative myocarditis in 7 of the 9 fetuses. Additional lesions observed in some fetuses were focal hepatic necrosis, nonsuppurative myositis, focal necrotizing placentitis, focal nonsuppurative pneumonia, and focal nonsuppurative nephritis. A few groups of Neospora caninum-like protozoan organisms were observed adjacent to necrotic foci in the brain of 2 fetuses and in the kidney of a third fetus. No other cause of abortion was detected. |
