-This is a '''zoonotic''', diarrhoea- causing, disease of cattle and other domestic livestock caused by the parasite [[Cryptosporidium|cryptosporidium]].It is a protozoan parasite that inhabits crypt cells of the intestine. Transmission of the disease is faeco- oral. The disease is sever in humans and can be fatal in the immunocompromised. It causes severe sickness and diarrhoea for up to two weeks.<br>

The disease is severe in humans and can be fatal in the immunocompromised. It causes severe sickness and diarrhoea for up to two weeks.
 == Clinical Signs ==
-Often seen in adolescent calves, may present as a sudden outbreak or as sporadic disease. Animals may have weight loss and and appear dull and depressed. Diarrhoea will be profuse and watery and may appear green/ black.

 == Diagnosis ==
-Clinical signs and age of cattle will provide a presumptive diagnosis. A faecal smear with&nbsp;'''Ziehl-Neelson''' (ZN) stain is diagnostic and if cryptosporidium is present then oocysts stain red against a blue/green background. Immunoassayscan also be performed to detect oocysts in faeces.
