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. Recent molecular analyses have suggested the need for taxonomic revision, and it is now sometimes referred to as Neobalantidium coli or ...
Balantidium coli lives in the cecum and colon of humans, pigs, rats, and other mammals. It is not readily transmissible from one species of host to another because it requires a period of time to adjust to the symbiotic flora of the new host. Once it has adapted to a host species, the protozoan can become a serious pathogen, especially in humans.

Aug 25, 2023 · The cyst represents the nonreplicating infective stage. B coli forms a large spherical cyst that may grow to 60 µm in diameter. The cyst contains a macronucleus, a micronucleus, and a granular cytoplasm. Cilia may be found in young cysts but never in mature cysts. The cysts can be demonstrated in semiformed and fully formed stools.
Mar 22, 2022 · Balantidium coli is a ciliated protozoan parasite, which causes intestinal and extraintestinal infections in humans. It is transmitted feco-orally by ingesting infective cysts with food and water. Urinary balantidiasis may occur through contamination (direct spread from the anal area), secondarily to rectovaginal fistula and following immune ...
Jan 5, 2022 · The ciliate Balantioides coli (syn. Balantidium coli) is the largest human parasitic protozoa, and can infect a wide range of hosts, with swine being the main reservoir. The parasite has a direct life cycle, with a vegetative form, the trophozoite, inhabiting the host intestine, and a resting cyst that is released into the environment in faeces.
