Mature cysts are passed with feces. Other potential animal reservoirs include rodents and nonhuman primates.
Cysts are less frequently encountered. Balantidium coli is passed intermittently and once outside the colon is rapidly destroyed. Image contributed by the Oregon Public Health Laboratory. Recommend on Facebook Tweet Share Compartir.
Image Gallery Balantidium coli cysts in wet mounts. Trophozoites are characterized by: The host most often acquires the cyst through ingestion of contaminated food or water.

DPDx is an education resource designed for health professionals and laboratory scientists. Trophozoites undergo encystation to produce infective cysts. Cysts acso the parasite stage responsible for transmission of balantidiasis. Life Cycle Cysts are the parasite stage responsible for transmission of balantidiasis.
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. Enter Email Address What’s this?

Some trophozoites invade the wall of the colon and multiply. Get Email Updates To receive email updates about this page, enter your email address: Some return to the lumen and disintegrate.
Clinical manifestations, when present, include persistent diarrhea, occasionally dysentery, abdominal pain, and weight loss. December 4, Page last updated: For an overview including prevention and control visit www. Note the visible cilia on the cell surface. Most cases are asymptomatic. 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.
Both Balantidium coli trophozoites and cysts are found in stool. Because pigs are an animal reservoir, human infections occur more frequently in areas where pigs are raised. December 4, Content source: Symptoms can be severe in debilitated persons.
Laboratory Diagnosis Laboratory Diagnosis Diagnosis is based on detection of trophozoites in stool specimens or in tissue collected during endoscopy.
Diagnosis is based on detection of trophozoites in stool specimens or in tissue collected during endoscopy. Morphologic comparison with other intestinal parasites. Following ingestion, excystation occurs in the small intestine, and the trophozoites colonize the large intestine.
