Image Gallery Balantidium coli cysts in wet mounts. Note the cytosome black arrow and the cli shaped macronucleus. Diagnosis is based on detection of trophozoites in stool specimens or in tissue collected during endoscopy.


Thus stool specimens should be collected repeatedly, and immediately examined or preserved to enhance morvologia of the parasite. Both Balantidium coli trophozoites and cysts are found in stool.

The trophozoites reside in the coi of the large intestine of humans and animals, where they replicate by binary fission, during which conjugation may occur. Some trophozoites invade the wall of the colon and multiply. Balantidium coli is passed intermittently and once outside the colon is rapidly destroyed.
