Balantidium coli


Also found in: Encyclopedia, Wikipedia.

Ba·lan·ti·di·um co·'li

a very large parasitic ciliate species, usually 50-80 mcm in length, reaching up to 200 mcm in pigs, found in the cecum or large intestine, swimming actively in the lumen; usually harmless in humans but may invade and ulcerate the intestinal wall, producing a colitis resembling amebic dysentery.

Balantidium coli

[bal′əntid′ē·əm]
Etymology: Gk, balantidion, little bag, kolon, colon
the largest and the only ciliated protozoan species that is pathogenic to humans, causing balantidiasis. The organism is seen in two life stages: the motile trophozoite and the encysted cercaria. It is a normal inhabitant of the domestic hog and is transmitted to humans by the ingestion of cysts excreted in hog feces, occurring either during direct contact with pigs, handling of fertilizer that contains pig excrement, or contact with a water supply contaminated with excrement.

Ademas de la caceria clandestina y la destruccion del habitat, las infecciones parasitarias juegan un rol importante en la capacidad de supervivencia de los primates, especialmente si se toma en cuenta que cada dia existe mayor contacto entre primates y humanos, dandose el riesgo de transmision de parasitos de humanos hacia los monos, especialmente de protozoarios como Balantidium coli, Entamoeba coli, E.
