Cryptosporidiosis is the emergent and significant microbiological pathogen, which has consequently impressed concern all over the world.This intracellular parasite infects more than 240 animals, including human, avain, mammal, reptile and amphibian.To date, eight zoonotic Cryptosporidium species and onegenotype have been recognized, namely, C.hominis, C.parvum, C.canis, C.felis,C.meleagridis, C.muris, C.suis, C.andersoni and C.parvum cervine genotype.Based on the previous data, the patients prevalence of Cryptosporidium infectionhave been found to be 4%~20% and 0.6%~20% in developed countries and developing countries, respectively.While in our country, the infection rate varies from 0.23% to 13.3%, and children are more vulnerable than adults.Transmissionof the parasites are transmitted by the fecal-oral route and contaminate environment, food and water.The review describes the biological characterization and molecular characterization of each species and genotype, which provide solid theoretical basis for the further research of parasite distribution, evolution characterization, and zoonotic transmission route.
