Abstract
The endogenous development of E. Tenella wild strain was observed in primary and secondary infected chicken to know protective immunity development on host. Twenty broiler chicks at three weeks old were infected with 5 x 103 oocyst of E. tenella. Morphological parasitic endogenous development was observed at 5 days pi, oocyst production calculated at 6 to 11 days pi for primary infection. Two weeks pi, the same procedure was performed for secondary infection. Total oocyst production at primary infection was higher than at secondary infection. Endogenous development disabilities of parasites occur as a result of protective immunity generated at the rst antigen exposure.
Key Words: endogenous development, E. tenella, protective immunity
