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.

Although there is controversy among authors regarding the use of epimastigotes for these trials, it is important to note that previous studies demonstrated a correlation between epimastigote, trypomastigote, and amastigote forms of T.
An enzyme immunoassay was reactive and an immunoblot of trypomastigote excreted-secreted antigens was positive, confirming the diagnosis.
evansi antibody revealed rounded or elongated structures, the latter resembling free trypomastigote forms in the neuropil in both equines (Figure 2C).
Trypanosomatides occur in different morphological forms in its life cycle viz amastigote (leishmanial), promastigote (leptomonad), epimastigote (crithidial), trypomastigote (trypanosomal) and opisthomastigote (herpetomonad).
It is important to clarify that previous studies demonstrate a correlation between epimastigote and trypomastigote forms of T.
Trypanosoma cruzi Epimastigogenesis: A Method for Studying Trypomastigote to Epimastigote Transformation In Vivo
Leishmain stain of blood film revealed trypomastigote form of Trypanosoma brucei having long cylinder body, central nucleus and undulating membrane with long flagellum arising from kinetoplast located at posterior end (Fig 1).
Inhibitory activities of lapachol and a- and b-lapachone derivatives have been reported against epimastigote and trypomastigote forms of Trypanosoma cruzi (Salas et al.
cruzi invades a variety of types of host cells, circulates in the blood stream in the form of a trypomastigote and proliferates inside the cytoplasm of those cells, as amastigote.
