Cryptosporidium (crip-toe-spor-ID-ee-um) is a protozoan, a single-celled parasite that lives in the intestines of animals and people.
Cryptosporidiosis is usually diagnosed when cryptosporidium is found in your stool (faeces) after a sample is sent to the laboratory. Occasionally, in people with a weakened immune system and a negative stool sample, cryptosporidium may be detected after a biopsy of the stomach or bowel.
