Other potential animal reservoirs include rodents and nonhuman primates.

Trophozoites undergo encystation to produce infective cysts. Because bapantidiasis 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. Morphologic comparison with other intestinal parasites. Thus stool specimens should be collected repeatedly, and immediately examined or preserved to enhance detection of the parasite. December 4, Content source: Enter Email Address What’s this?

Following ingestion, excystation occurs in the small intestine, and the trophozoites colonize the large intestine. Some return to the lumen and disintegrate.

Trophozoites are characterized by: Cysts are less frequently encountered.

Note the cytosome black arrow and the bean shaped macronucleus. Cysts are the parasite stage responsible for transmission of balantidiasis.

Symptoms can be severe in debilitated persons. Most cases are asymptomatic. Diagnosis is balantixiasis on detection of trophozoites in stool specimens or in tissue collected during endoscopy. For an overview including prevention and control visit www.

DPDx is an education resource designed for health professionals and laboratory scientists. Clinical manifestations, when present, include persistent diarrhea, occasionally dysentery, abdominal pain, and weight loss.


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. Balantidium coli is passed intermittently and once outside the colon is rapidly destroyed.
