Balantidium coli

Balantidium coli is a worldwide distributed ciliate of highly variable size (30-150 im long). It is frequently found as an inhabitant of the large intestine of monkeys, rats, and in particular pigs. It is also found, more rarely, in humans, in whom it occasionally causes intestinal necrosis and inflammation with ulceration. The disease is transmitted through spherical cysts (40-60 im) from host to hoston the fecal-oral route. Diagnosis involves detection of cysts or vegetative forms in fecal samples.
