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 ...
Aug 25, 2023 · Balantidiasis (also known as balantidiosis) is defined as large-intestinal infection with Balantidium coli, which is a ciliated protozoan (and the largest protozoan that infects humans). B coli is known to parasitize the colon, and pigs may be its primary reservoir. Trophozoite of Balantidium coli in colon.
Nov 1, 2021 · Abstract. Balantioides coli is a protozoan that infects different hosts species, including humans, with zoonotic transmission. The parasite, which lives in the large intestine and in other organs, can lead to serious infections that may culminate in death. Information about human balantidiasis is generally still very scanty.

Balantidium coli exists in either of two developmental stages: trophozoites and cysts. In the trophozoite form, they can be oblong or spherical, and are typically 30 to 150 μm in length and 25 to 120 μm in width. It is its size at this stage that allows Balantidium coli to be characterized as the largest protozoan parasite of humans.
Living trophozoites and cysts are yellowish or greenish in color. Transmission. Balantidium is the only ciliated protozoan known to infect humans. Balantidiasis is a zoonotic disease and is acquired by humans via the feco-oral route from the normal host, the domestic pig, where it is asymptomatic. Contaminated water is the most common mechanism ...
Nov 1, 2021 · Introduction. Balantidiasis is a parasitic disease caused by the protozoan Balantioides coli, formerly known as Balantidium coli, a protozoan that infects animals including pig, non-human primates and humans, and has a zoonotic transmission potential (Chistyakova et al., 2014; Ahmed et al., 2020). Infection in humans by this parasite is known ...
