The ciliate Balantidium coli, 50–200 μm in length (Fig. 2, page 158) lives in the lumen of the colon of humans, pigs, rodents, and many mammals but is often invasive, forming deep ulcers with undermining margins. The balantidia are found in these ulcers and extend the ulcer base to the muscularis and occasionally beyond, leading to perforation.
