Neospora caninum is a protozoan parasite that was mistaken for Toxoplasma gondii until the mid-1980s. Although it was first identified in dogs, neosporosis has recently been recognized as a major cause of abortion in cattle, particularly dairy cattle, worldwide. The infection can be transmitted vertically over several generations, but how the cows acquired the initial infection is unknown. If horizontal transmission occurs, it is apparently infrequent. At present veterinarians can diagnose neosporosis and can document whether neosporosis is contributing to reproductive tosses at a dairy. Until the definitive host is identified or a vaccine against the disease is developed, veterinarians can make few specific recommendations for prevention of this disease. There is currently no evidence that neosporosis poses any zoonotic risk. This workshop was made possible by special funds from Bayer AG and Bayer Corporation.
