Serological diagnosis of Neospora caninum infection

Since the first isolation of the apicomplexan parasite Neospora caninum, a range of serological assays have been developed for use in dogs, cattle and a variety of other potential host species. The tests include the indirect fluorescent antibody test, the direct agglutination test and different enzy me-linked immunosorbent assays. This article reviews the principles and pro perties of the available tests which are discussed in relation to different applications. (C) 1999 Australian Society for Parasitology Inc.
