Interpretive Summary: Neospora caninum is a single celled parasite. It causes abortion in cattle and paralysis in companion animals. It is the most important cause of abortion in dairy cattle. Dogs and coyotes are its definitive hosts and main reservoirs of infection. This parasite is transmitted efficiently from the cow to the calf transplacentally. Toxoplasma gondii and Sarcocystis species are related parasites that can also cause abortion in livestock. Scientists at the Beltsville Agricultural Research Center and Virginia Tech, Blacksburg, review clinical neosporosis, toxoplasmosis and sarcocystosis. The results will be of interest to biologists, parasitologists, and veterinarians.

Technical Abstract: Neospora caninum, Sarcocystis spp., and Toxoplasma gondii are related coccidian parasites that can cause abortion and neonatal mortality in animals. In addition, T. gondii and certain species of Sarcocystis are zoonotic. This paper reviews information on etiology, diagnosis, control and prevention of these diseases.
