Note the visible cilia on the cell surface. December 4, Page last updated: Life Cycle Cysts are the parasite stage responsible for transmission of balantidiasis. DPDx is an education resource designed for health professionals and laboratory scientists. Enter Email Address What’s this?
Following ingestion, excystation occurs in the small intestine, and the trophozoites colonize the large intestine. Trophozoites are characterized by: Some trophozoites invade the wall of the colon and multiply.
Diagnosis is based on detection of trophozoites in stool specimens or in tissue collected during endoscopy. December 4, Co,i source: Image contributed by the Oregon Public Health Laboratory.

Balantidium coli is passed intermittently and once outside the colon is rapidly destroyed. Trophozoites undergo encystation to produce infective morfplogia. Symptoms can be severe in debilitated persons.
Some return to the lumen and disintegrate. Laboratory Diagnosis Laboratory Diagnosis Diagnosis is based on detection of trophozoites in stool specimens or in tissue collected during mordologia.
Mature cysts are passed with feces. Clinical manifestations, when present, include persistent diarrhea, occasionally dysentery, abdominal pain, and weight loss.

Morphologic comparison with other intestinal parasites. Note the cytosome black arrow and the bean shaped macronucleus.
Thus stool specimens should be collected repeatedly, and immediately examined or preserved to enhance detection of the parasite. Both Balantidium coli trophozoites and cysts are found in stool.
The host most often acquires the cyst through ingestion of contaminated food or water. Morfolohia directly to search Skip directly to A to Z list Skip directly to navigation Skip directly to page options Skip directly to site content.

Because pigs are an animal reservoir, human infections occur more frequently in areas where pigs are raised. The trophozoites reside in the lumen of the large intestine of balanidium and animals, where they replicate by binary fission, during which conjugation may occur.
