Trypanosoma

Genus of parasitic flagellate protist in the Kinetoplastea class

Trypanosoma

Trypanosoma is a genus of kinetoplastids (class Trypanosomatidae), a group of unicellular parasitic flagellate protozoa under the phylum Euglenozoa. The name is derived from the Ancient Greek trypano- (borer) and soma (body) because of their corkscrew-like motion. Most trypanosomes are heteroxenous (requiring more than one obligatory host to complete life cycle) and most are transmitted via a vector.
