epimastigote

ep·i·mas·ti·gote

(ep'i-mas'ti-gōt),
An insect stage of Trypanosomatide infection. Term replacing "crithidial stage," to avoid confusion with the insect-parasitizing flagellates of the genus Crithidia. In the epimastigote stage, the flagellum arises from the kinetoplast alongside the nucleus and emerges from the anterior end of the organism; an undulating membrane is present.
[epi- + G. mastix, whip]

epimastigote

a developmental stage in trypanosomes. The undulating membrane is shortened and the axoneme and the kinetoplast are anterior to the nucleus; in the previous stage they are near the tail and behind the nucleus. This stage occurs usually in the arthropod host. Called also crithidial stage.

Trypanosomatides occur in different morphological forms in its life cycle viz amastigote (leishmanial), promastigote (leptomonad), epimastigote (crithidial), trypomastigote (trypanosomal) and opisthomastigote (herpetomonad).
Thus, the aim of this study was to investigate the antitrypanosomal activity of gallic acid and its esters against epimastigote forms of Trypanosoma cruzi.
Trypanosoma cruzi Epimastigogenesis: A Method for Studying Trypomastigote to Epimastigote Transformation In Vivo
Inhibitory activities of lapachol and a- and b-lapachone derivatives have been reported against epimastigote and trypomastigote forms of Trypanosoma cruzi (Salas et al.
Dentro del insecto los parasites se encuentran en forma epimastigote, posteriormente se transforman en la forma tripomastigote.
However, the specific status of the parasites should be determined by molecular techniques because it has been demonstrated that morphollogically is hard to differentiate epimastigote stage of Blastocrithidia from epimastigote stage of Trypanosoma present in tabanids (Hoare 1972, Krinsky & Pechuman 1975, Desquesnes 2004) and the transmission mechanism should be established too by controlled studies.
lewisi has two biological forms: epimastigote, in the insect's intestine and trypomastigote, in the rat blood (1).
