Animal-Like Flagellates

In the Phylum Mastigophora, the cells are equipped with one to several whiplike flagella used for movement. All are heterotrophs which are either free-living species in freshwater and marine habitats, or internal parasites.

Trichomonas vaginalis is spread by sexual contact and can cause damage to urinary and reproductive tracts.

The cyst-forming Giardia lamblia typically acquired from infested drinking water such as in mountain streams, usually causes mild diarrhea, but in some persons can cause death.

Members of the genus Trypanosoma cause African sleeping sickness and Chagas disease.
