Balantidium coli

This parasite is a ciliate protozoan. The trophozoites measure 50 to 200 microns. Viable organisms in unfixed stool samples are very active moving across the field of view in a rotary motion.

This microphotographic image was taken at the Oregon State Public Health Laboratory. The OSPHL Parasitology Department is equipped with a Leica DC 200 digital camera mounted on a Leica DMLS microscope. This equipment is used in conjunction with the Division of Parasitic Diseases (DPDx) at the Centers for Disease Control & Prevention (CDC) to aid in the rapid diagnosis of unusual or difficult parasitic diseases using digital images and the Internet.
