It is a [[:Category:Protozoa|protozoan parasite]] that inhabits crypt cells of the intestine. Transmission of the disease is faeco-oral. 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 and age of cattle will provide a presumptive diagnosis. A faecal smear with '''Ziehl-Neelson''' (ZN) stain is diagnostic and if ''Cryptosporidium'' is present then oocysts stain red against a blue/green background. Immunoassays can also be performed to detect oocysts in faeces.
