For an overview including prevention and control visit www. 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.

Laboratory Diagnosis Laboratory Diagnosis 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 detection of the parasite. Other potential animal reservoirs include rodents and nonhuman primates.

December 4, Content source: Image Cljnico Balantidium coli cysts in wet mounts. Trophozoites undergo encystation to cliico infective cysts. Balantidium coli is passed intermittently and once outside the colon is rapidly destroyed.

Note the cytosome black arrow and the bean shaped macronucleus. Some return to the lumen and disintegrate. Diagnosis is based on detection of trophozoites in stool specimens or in tissue collected during endoscopy.
