"This article is about the order Trypanosomatida, see also the genus Trypanosoma.Trypanosomatids are a group of kinetoplastid protozoa distinguished by having only a single flagellum. The name is derived from the Greek trypano (borer) and soma (body) because of the corkscrew-like motion of some trypanosomatid species. All members are exclusively parasitic, found primarily in insects. A few genera have life-cycles involving a secondary host, which may be a vertebrate, invertebrate or plant."@en .
