Trypanosoma is part of the phylum Euglenozoa. [3] The name is derived from the Ancient Greek trypano-(borer) and soma (body) because of their corkscrew-like motion. Most trypanosomes are heteroxenous (requiring more than one obligatory host to complete life cycle) and most are transmitted via a vector.
The life cycle of the Trypanosoma brucei parasites. Trypanosoma brucei gambiense accounts for the majority of African trypanosomiasis cases, with humans as the main reservoir needed for the transmission, while Trypanosoma brucei rhodesiense is mainly zoonotic, with accidental human infections. [20]
Trypanosoma brucei is a species of parasitic kinetoplastid belonging to the genus Trypanosoma that is present in sub-Saharan Africa.Unlike other protozoan parasites that normally infect blood and tissue cells, it is exclusively extracellular and inhabits the blood plasma and body fluids. [1]
This heteroxenous life cycle typically includes the intestine of a bloodsucking insect and the blood and/or tissues of a vertebrate. Rarer hosts include other bloodsucking invertebrates, such as leeches, [8] and other organisms such as plants. Different species go through a range of different morphologies at different stages of the life cycle ...
In a recent study comparing Brazilian isolates in rats and primates, it was found the DNA sequences were the same when considering Trypanosoma lewisi. This further proves the potential of Trypanosoma lewisi's ability to infect human beings, despite being rare in most cases. [10] Life cycle of Trypanosoma lewisi
Chagas disease, also known as American trypanosomiasis, is a tropical parasitic disease caused by Trypanosoma cruzi.It is spread mostly by insects in the subfamily Triatominae, known as "kissing bugs".
Trypanosoma cruzi is a species of parasitic euglenoids. Among the protozoa, the trypanosomes characteristically bore tissue in another organism and feed on blood (primarily) and also lymph. This behaviour causes disease or the likelihood of disease that varies with the organism: Chagas disease in humans, dourine and surra in horses, and a ...
Trypanosoma vivax is a parasite species in the genus Trypanosoma. ... Instead it infects and completes an abbreviated life cycle only in the vector's proboscis.
