Balantidium coli: Parasitology and Characteristics

The current name of the organism initially called Paramecium coli is Neobalantidium spp.

The cyst of Balantidium coli is spherical to ovoid in shape.

Mucocysts in Balantidium coli function in extrusion.

The mode of transmission for Balantidium coli is through ingestion of contaminated food and water.

The trophozoites of Balantidium coli inhabit the cecum and large intestine.

Trophozoites attacking the intestinal epithelium result in ulcer formation.

The trophozoites of Balantidium coli reproduce through asymmetric binary fission.

Hyaluronidase in Balantidium coli infection helps in breaking down the host's tissues.

The natural host of Balantidium coli is pigs.
