Note the cytosome black arrow and the bean shaped macronucleus. Balantidium coli is passed intermittently and once outside the colon is rapidly destroyed.

Thus stool specimens should be collected repeatedly, and immediately examined or preserved to enhance detection of the parasite. Clinical manifestations, when present, include persistent diarrhea, occasionally dysentery, abdominal pain, and weight loss.


Some trophozoites invade the wall of the colon and multiply. Note the visible cilia on the cell surface. Enter Email Address What’s this?

Cysts are less frequently encountered.

Diagnosis is based on detection of trophozoites in stool specimens or in tissue collected during endoscopy.

Mature cysts are passed with feces. Some return to the lumen and disintegrate. Following ingestion, excystation occurs in the small intestine, and the trophozoites colonize the large intestine. Image contributed by the Oregon Public Health Laboratory. Because pigs are an animal reservoir, human infections occur more frequently in areas where pigs are raised. Both Balantidium coli trophozoites and cysts are found in stool. Linking to a non-federal site does not constitute an endorsement by HHS, CDC or any of its employees of the sponsors or the information and products presented on the site.


The trophozoites reside in the lumen of the large intestine of humans and animals, where they replicate by binary fission, during which conjugation may occur. The host most often acquires the cyst through ingestion of contaminated food or water. Trophozoites undergo encystation to produce infective cysts.
