Neosporosis is a common disease of cattle that is caused by the protozoan (one-celled) parasite, Neospora caninum. Infection of pregnant cows causes abortion. The first recognized outbreak of neosporosis abortion occurred in a New Mexico dairy and was reported in 1989. Ten years later, evidence of neosporosis has been found on every continent but Antarctica. Neospora infection is the single most common cause of abortion in dairy cattle in New Zealand, Great Britain, the Netherlands, and California. In the U.S. neosporosis has been diagnosed throughout the country, including Colorado. Beef cows can also contract this disease, but it is more common in intensively managed dairy cattle operations.
