The balantidiasls reside in the lumen of the large intestine of humans and animals, where they replicate by binary fission, during which conjugation may occur.
The host most often acquires the cyst through ingestion of contaminated food or water. Morphologic comparison with other intestinal parasites. Cysts are less frequently casp. Clinical manifestations, when present, include persistent diarrhea, occasionally dysentery, abdominal pain, and weight loss.
Other potential animal reservoirs include rodents and nonhuman primates. Most cases are asymptomatic. Following ingestion, excystation occurs in the small intestine, and the trophozoites colonize the large intestine.
Some trophozoites invade the wall of the colon and multiply. Some return to the lumen and disintegrate.

Trophozoites balantidiawis characterized by: Diagnosis is based on detection of trophozoites in stool specimens or in tissue collected during endoscopy. December 4, Content source: Life Cycle Cysts are the parasite stage responsible for transmission of balantidiasis.
Trophozoites undergo encystation to produce infective cysts. Thus stool specimens should be collected repeatedly, and immediately examined or preserved to enhance detection of the parasite. Balantidium coli is passed intermittently and once outside the colon is rapidly destroyed. Enter Email Address What’s this?

Note the visible cilia on the cell surface. Get Email Updates To receive email updates about this page, enter your email address: Both Balantidium coli trophozoites and cysts are found in stool. Cysts are the parasite stage responsible for transmission of balantidiasis. Because pigs are an animal reservoir, human infections occur more frequently in areas where pigs are raised. Laboratory Diagnosis Laboratory Diagnosis Diagnosis is based on detection of trophozoites in stool specimens or in tissue collected during endoscopy.
