Balantidium
A genus of ciliates (family Balantidiidae) found in the digestive tract of vertebrates and invertebrates. [G. balantidion, dim of ballantion, a bag]
- B. coli a very large parasitic ciliate species, usually 50–80 μm in length, reaching up to 200 μm in pigs, found in the cecum or large intestine, swimming actively in the lumen; usually harmless in humans but may invade and ulcerate the intestinal wall, producing a colitis resembling amebic dysentery.
- B. suis a species originally considered distinct from the ciliate parasite of man, B. coli, but now considered synonymous with it; nonpathogenic in swine.
