Assessment of protective immunity of wild E.tenella oocyst protein against heterologous challenge done in chickens. Immunization applied on 4thand 18thday of age subcutaneously with protein dose of 50 μg per chicken. Immunized chickens were challenged at 32ndday of age, demonstrated oocyst protein of E. tenella provide protection around 57% compared to unimmunized chickens, while parasite development, oocysts number and cecal lesion of the chickens immunized decreased significantly compared unimmunized groups.The study results demonstrated relative protection against coccidia by the use of E. tenella oocyst protein as vaccine in broilers.
