Cryptosporidium spp.are zoonotic intestinal protozoan with a wide distribution around the world.Cryptosporidiosis is mainly transmitted by fecal-oral route.Rodents are important hosts of Cryptosporidium spp.and in close contact with humans,making them one of the potential sources of Cryptosporidium infections in humans.Re-search data showed that 23 provinces had conducted surveys on Cryptosporidium infections in rodents in China,and there were differences in Cryptosporidium infections in rodents from different sources and uses.This paper summarized the distribution of species/genotypes and subtypes of Cryptosporidium infection in rodents from different regions,sources and uses in China,and analyses the effects of Cryptosporidium infections in rodents on other animals as well as the surrounding environment.Considering that Cryptosporidium spp.detected in rodents have also been detected in humans,other animals and their surroundings,the role of rodents in the transmission of Cryptosporidium spp.at the human-animal-environment interface cannot be ignored.
