The three basic developmental stages (trypomastigote, amastigote, and epimastigote) are schematically shown in Figure 2 a-c, based on images obtained using transmission electron microscopy [2 ...

A drawing of a trypomastigote cell is shown, with three cross-sections (A-C) indicated. The drawing was made from a single frame of a video of a live, swimming, slender bloodstream form cell....

In general, the epimastigote and promastigote forms of digenetic trypanosomatids are found in the vector, the trypomastigote form is found in the mammalian host and the amastigote form is...

The phenotypic assays revealed potent activity of the root extract against different forms (trypomastigote and intracellular forms) and strains (Y and Tulahuen), with a compound concentration...

Trypomastigotes are the host infective, non-replicative stages that can invade any nucleated cell, while amastigotes replicate in the cytosol of animal cells until they differentiate back to trypomastigotes to be released to the blood circulation.

Trypomastigotes, the flagellated stage of trypanosomes found in peripheral blood, are large, extracellular protozoa that have an elongated or “blade-shaped” body with an undulating membrane, a tapering posterior end, and a short flagellum directed anteriorly. Belkisyolé Alarcón de …

These specimens are excellent examples of trypomastigote morphology. Locate the following: nucleus, kinetoplast, kinetosome (if visible), undulating membrane, and free flagellum. Note that the kinetoplast is posterior to the nucleus in position and the very long undulating membrane that are characteristic of this trypanosomatid body form.

2018年2月6日 · Trypanosoma cruzi uses several strategies to survive in different hosts. A key step in the life-cycle of this parasite is metacyclogenesis, which involves various morphological, biochemical, and genetic changes that induce the differentiation of non-pathogenic epimastigotes into pathogenic metacyclic trypomastigotes.

A typical trypomastigote has a large, subterminal or terminal kinetoplast, a centrally located nucleus, an undulating membrane, and a flagellum running along the undulating membrane, leaving the body at the anterior end. Trypanosomes measure from 12 to 30 µm in length.

In trypomastigotes (left) the kinetoplast is posterior to the nucleus, whereas in epimastigotes (right) the kinetoplast is typically anterior to the nucleus (1). In this category, though not as...
