Citation: Dubey, J.P. 2003. Neosporosis in cattle. Journal of Parasitology 89:42-56. Interpretive Summary: Neospora caninum is a single celled parasite of livestock and companion animals. It causes abortion in livestock and paralysis in companion animals. A scientist from the Beltsville Agricultural Research Center reviews available information on neosporosis in cattle. The information will be of interest to biologists, parasitologists and bovine practioners.
Technical Abstract: Neospora caninum is a major pathogen of cattle and dogs that occasionally causes clinical infections in horses, goats, sheep, and deer. The domestic dog is the only known definitive host for N. caninum. In cattle N. caninum is a major cause of bovine abortion in many countries and is one of the most efficiently transmitted parasites with up to 90% of some bovine herds infected. Trasnplacental transmission in cattle is considered the major route of transmission. To elicit protective immunity against abortion in persistently infected cows is a considerable challenge.
