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 as seen in a wet mount of a stool specimen. The organism is surrounded by cilia. Balantidium coli has two developmental stages, a trophozoite stage and a cyst stage. In trophozoites, the two nuclei are visible.

Oct 23, 2023 · Trophozoites undergo encystation to produce infective cysts. Some trophozoites invade the wall of the colon and multiply; some return to the lumen and disintegrate. Mature cysts are passed in the stool and can remain viable for up to two weeks in the environment [ 8 ].
Aug 25, 2023 · [ 21] Cyst. 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,...
Balantidium cysts are larger (40 to 60 μm) than ameba cysts and are binucleate (macro- and micronuclei), and at times the trophic organism can be seen spinning within the cyst wall due to ciliary activity. The two organisms are found in the trophic state in diarrheic stools.
