ABSTRACT
Sarcocystis pose harm on human and domestic animal.The acute infection of Sarcocystis could cause abortion,death and caused huge economic losses for farms.Cattle were intermediate host of Sarcocystis.Consumption beef containing Sarcocystis cysts endanger human health,causing abdominal pain and diarrhea.The positive rate was 42.44 ％-98.72 ％ globally,and it was reported 3.64％-98.1％ in China.Five Sarcocystis species were confirmed in cattle,S.cruzi,S.hirsuta,S.hominis,S.rommeli,and S.heydorni.Three species have been reported in cattle from China:S.cruzi,S.hominis,and S.heydorni.It had been verified that S.cruzi and S.hominis had strong pathogenicity to cattle and human.This paper reviews the life cycle,epidemiology,classification,pathogenicity and diagnosis of cattle Sarcocystis,providing reference for supervisory and control Sarcocystis in beef.
