Induction of protective immunity through the parasite endogenous development and oocyst production during challenge test due to the previous E. maxima low doses exposure was studied. Forty ve broilers were divided into 3 groups. Group 1: chickens were administered aquadest. Group 2 and 3: chickens were inoculated with 100 & 200 E. maxima oocysts, respectively. Fourteen days after 1st infection, each group was challenged with 5000 E. maxima oocysts. Post challenge of 4 days the endogenous development of parasites, oocysts production was calculated. The endogenous development of parasites has decreased as a result of protective immunity due to rst antigen exposure so that multiplication of parasites became decreased

Key Words: E. maxima, low doses, protective immunity
