Development and application of an indirect ELISA to detect antibodies to in cattle based on a chimeric protein rSRS2-SAG1-GRA7.

is an important apicomplexan parasite causing neosporosis in cattle. The disease is recognized as one of the most important cause of reproductive problems and abortion in cattle worldwide. In this context, we developed an indirect enzyme-linked immunosorbent assays (ELISA) with chimeric protein rSRS2-SAG1-GRA7 to diagnose antibodies to -infection.
