Balantidium coli Homepage
Common name: Balantidiasis
The trophozoite is oval in shape and averages 75 x 50 um in size, but varies from 30 to 100 um in width, and 30 to 300 um in length.
Balantidium coli is widely epidemic among the pig population of the world. The adult resides in the large intestine and cecum. Cysts are expelled in feces and reinfect host via accidental ingestion. The parasite excysts in the host intestine. The parasite normally feeds upon fecal material, starch granules, and cell fragments. The ciliates often invade the mucosa and submucosa of the intestines and produce severe ulcers, that are often flask like in shape.
NOTE: Trichuris suis, whipworm infection, often occurs in conjunction with Balantidium coli infection in pigs.
