Trypanosoma rangeli: sequence analysis of beta-tubulin gene suggests closer relationship to Trypanosoma brucei than to Trypanosoma cruzi

Trypanosoma rangeli, the only trypanosome besides Trypanosoma cruzi to infect humans in the Americas, shows an important geographical overlap with the agent of Chagas disease, and its taxonomic position has been the source of some controversy. This study utilizes beta-tubulin gene sequences for investigating the phylogeny of this species. All trees, produced with the different algorithms utilized, always grouped T. rangeli with Trypanosoma brucei in preference to T. cruzi. In addition evidence suggesting that the genus Trypanosoma may be polyphyletic was found.

African Trypanosomiasis

African trypanosomiasis, also known as sleeping sickness, is an insect-borne parasitic disease of humans and other animals. It is caused by protozoa of the species Trypanosoma brucei and almost invariably progresses to death unless treated. Discover the latest research on African trypanosomiasis here.
