Bovine neosporosis: clinical and practical aspects.

Neospora caninum is a protozoan parasite with a wide host range but with a preference for cattle and dogs. Since the description of N. caninum as a new genus and species in 1988, bovine neosporosis has become a disease of international concern as it is among the main causes of abortion in cattle. At present there is no effective treatment or vaccine. This review focuses on the epidemiology of the disease and on prospects for its control in cattle. Finally, based on the implications of clinical findings reported to date, a set of recommendations is provided for veterinarians and cattle farmers.
