Cryptosporidiosis is an uncommon infection in foals caused by the parasitic Cryptosporidium parvum protozoan parasite. The source of the infection is egg cysts (oocysts) containing the parasite. The oocysts are excreted in the feces of infected horses or other infected species (such rodens or farm cats. Simultaneous infection (especially with rotavirus or coronavirus), are common and diarrhea is more severe in these mixed infections.
Cryptosporidium lives in the intestine of infected humans or animals. Millions of crypto parasites can be released in a bowel movement from an infected human or animal. Consequently, Cryptosporidium is found in soil, food, water, or surfaces that have been contaminated with infected human or animal feces. A person becomes infected by swallowing Cryptosporidium parasites. You cannot become infected through contact with blood. Crypto can be spread:
