Abstract

The endogenous development of E. necatrix was observed at primary and secondary infected chicken to know protective immunity development on host. The present study used 25 broiler chickens at 3 weeks old were divided into 2 groups. Group 1 was 10 chickens administered aquades, after 14 days then challenged 5 x 103 E. necatrix oocysts, 4 days post challenged 5 chickens were sacrificed to observe morphological endogenous development of parasites by histopathological changes examination, while oocysts production was calculated on 5 other chickens from day 6 to 12 post challenged. Group 2 was 15 chickens inoculated 5 x 102 E. necatrix oocysts, 4 days pi 5 chickens were sacrificed to observe morphological endogenous development of parasites by histopathological changes examination for primary infection. The results show that group 1, in si, parasites were development and proliferation well, whereas group 2, in si was seen few development and proliferation of parasites. In conclusion, the endogenous development disabilities of parasites occur as a result of protective immunity generated resulting from the first antigen exposure so that proliferation and multiplication of parasites became decreased
