Most cases are asymptomatic. Enter Email Address What’s this? Balantidium coli is passed intermittently and once outside the colon is rapidly destroyed.

Both Balantidium coli trophozoites and cysts are found in stool. Other potential animal reservoirs include rodents and nonhuman primates.


The host balabtidium often acquires the cyst through ingestion of contaminated food or water. Cysts are less frequently encountered. DPDx is an education resource designed for health professionals and laboratory scientists. Cysts are the parasite stage responsible for transmission of balantidiasis. 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. Following ingestion, excystation occurs in the small intestine, and the trophozoites colonize foli large intestine. December 4, Content source: Recommend on Facebook Tweet Share Compartir. Image Gallery Balantidium coli cysts in wet mounts. Trophozoites are characterized by: Note the cytosome black arrow and the bean shaped macronucleus.

Laboratory Diagnosis Laboratory Diagnosis Diagnosis is based on detection of trophozoites in stool specimens or in tissue collected during endoscopy. Mature cysts are passed with feces. Morphologic comparison with other intestinal parasites.

Trophozoites undergo encystation to produce infective cysts.

Symptoms can be balantidikm in debilitated persons. Some trophozoites invade the wall of the colon and multiply. 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. Life Cycle Cysts are the parasite stage responsible for transmission of balantidiasis.

Note the visible cilia on the cell surface.

Clinical manifestations, when present, include persistent diarrhea, occasionally dysentery, abdominal pain, and weight loss.
