 Trypanosoma - MicrobeWiki
Trypanosoma's cell structure plays a vital role in allowing the cell to morph into three forms (trypomastigote, epimastigote, and amastigote) during its lifecycle, depending on where the cell is located in the host's anatomy.
Trypanosoma brucei and Trypanosoma cruzi are parasites--therefore the ecology of their vector and host is the ecology of the species itself.
Trypanosoma cruzi is found in many countries in the Americas, and is carried by insects to animals and human in much the same way as its African counterpart, although rather than the tsetse fly, the vecters are bedbugs or "assassin" flies.

  Trypanosoma - Wikipedia, the free encyclopedia
Trypanosoma is a notable genus of trypanosomes, a monophyletic
Trypanosoma undergo a complex lifecycle which may include several different morphological forms especially in the species which are transmitted by invertebrates.
They may go through a variety of different forms in the invertebrate host, but in the vertebrate host the cells take a characteristic form called a trypomastigote, where the flagellum is runs from the posterior to the anterior of the cell and is connected by an undulating membrane.

 TRYPANOSOMA CRUZI: TAXONOMY, MORPHOLOGY AND LIFE CYCLE
Trypanosoma cruzi is a flagellate of the Kinetoplastida Order, Family Trypanosomatidae, characterized by the presence of one flagellum and a single mitochondrion in which is situated the Kinetoplast, a specialized DNA-containing organelle.
The identification of this parasite by morphological and biological features does not offer difficulties and differential is only required for Trypanosoma rangeli, a non-pathogenic flagellate which infects humans in some areas of Central and South America and is transmitted by some of the same vectors that transmit T. cruzi.
T. cruzi is not a homogeneous population and is composed rather by a pool of strains which circulate in both the domestic and sylvatic cycles involving humans, vectors and animal reservoirs of the parasite.

 Trypanosoma evansi Isolated from Capybara
A study was conducted to determine the morphological and biometric characteristics of Trypanosoma isolated from 50 capybaras animals, raised in captivity in the Peruvian Amazon.
Trypanosoma was found in 14 blood samples using the microhaematocrit, wide drop, and Giemsa-stain methods and T.
However, morphological studies on Trypanosoma in wild animals have not been performed in the tropics of Perú and therefore, the objective of the present study was to determine the morphological and biometric characteristics of Trypanosoma isolated from animals raised in captivity in the Peruvian Amazon.

Trypanosoma (Herpetosoma) lewisi is a trypanosome of the sub-genus Herpetosoma (Stercoraria section), parasite of rats (Rattus rattus and Rattus norvegicus) transmitted by fleas.
Trypanosoma lewisi infections in rat colonies can interfere with research protocols and fleas of wild rats are often the source of such infections.
The nucleus is anterior, the kinetoplast is far from the posterior extremity, which is very sharp and thin and the kinetoplast is oval, placed transversally to the body (fig 2 and5).
