Trophozoite,macrogamout,microgamout, typeⅠmeront,typeⅡmeront and sporozoite in the development of C.andersoni were observed by TEM.The proliferation of C.andersoni was significantly inhibited by 1.25μg/ml NTZ and 0.31μg/ml GAs.Treated with 20μg/ml NTZ and 5μg/ml GAs respectively,the numbers of C.andersoni were only 0.29%and 0.66%compared with the untreated.
