Balantidium (= Neobalantidium) (= Balantioides) coli, a large ciliated protozoan, is the only ciliate known to be capable of infecting humans. It is often associated with swine, the primary reservoir host.
Balantidium coli - Wikipedia
Balantidium coli has two developmental stages, a trophozoite stage and a cyst stage. In trophozoites, the two nuclei are visible. The macronucleus is long and sausage-shaped, and the spherical micronucleus is nested next to it, often hidden by the macronucleus.

Balantidium coli is the largest intestinal protozoan of humans and the only ciliate (Fig. 93.6). 283,284 It is a rare cause of diarrhea and inflammatory colitis. The trophozoite ranges in size from 60 to 70 µm (up to 200 µm), is usually ovoid in shape, and has a large, kidney-shaped macronucleus with a small micronucleus often lying in its ...

Balantidiasis is infection by Balantidium coli, the larg-est protozoan parasite and the only ciliate parasite known to infect humans. Malmsten first described the organism in 1857 in 2 patients with severe diarrhea; one of these infec-tions was fatal.1. Balantidiasis is also known as balantidiosis, balantidial dysentery, and ciliary dysentery.
Balantidium coli is a ciliated parasitic protozoan known to infect the intestines of humans and other mammals. The organism has distinctive large, kidney-shaped macronuclei, and an elliptical micronucleus. It produces infectious cysts in the host's intestines, leading to its life cycle.
