Balantidium coli is a large ciliated protozoan that causes balantidiasis, a parasitic infection of the large intestine and appendix. Cysts are the infectious stage and are transmitted by ingestion of contaminated food or water.
Balantidium coli life cycle Infection occurs when a host ingests a cyst, which usually happens during the consumption of contaminated water or food. [1] [6] Once the first cyst is ingested, it passes through the host's digestive system. [4]

Balantidium coli is an intestinal protozoan parasite that causes the infection called balantidiasis. While this type of infection is uncommon in the United States, humans and other mammals can become infected with Balantidium coli by ingesting infective cysts from food and water that is contaminated by feces.
May 15, 2024 · Balantidium coli infects the large intestine in humans and produces infective microscopic cysts that are passed in the feces, potentially leading to re-infection or infection of others. People compromised immune systems are the most likely to experience more severe signs and symptoms. These include persistent diarrhea, dysentery, abdominal pain ...

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.
Balantidium coli and balantidiosis, the subjects of this review, barely register among infectious protozoan diseases. Balantidium is the only ciliated protozoon known to infect humans and is the largest protozoon infecting humans and nonhuman primates. Balantidiosis is a zoonotic disease and is acquired by humans via the fecal-oral route from ...
