trypomastigote

tryp·o·mas·ti·gote

(trip'ō-mas'ti-gōt),
Term to replace the older term, "trypanosome stage," which was often confused with the flagellate genus Trypanosoma. It denotes the stage (ineffective stage for South American trypanosomiasis and African trypanosomiasis, and the only stage found in humans in the latter illness) in which the flagellum arises from a posteriorly located kinetoplast and emerges from the side of the body, with an undulating membrane running along the length of the body.
[G. trypanon, auger, + mastix, whip]

trypomastigote

(trip″ŏ-mas′ti-gōt″) [fr. tryp(anosome) + mastigote]
Any of the circulating forms of the protozoan parasite, Trypanosomacruzi. They swim and feed in the blood and may be transmitted from person to person (e.g. in blood transfusions) or from mother to developing fetus across the placenta.

trypomastigote

the characteristic developmental stage of trypanosomes, usually in the vertebrate host but may be in the invertebrate. A leaf-like form with an undulating membrane and often a free flagellum.
