Scientific classification
T. rangeli
Binomial name
Trypanosoma rangeli
Tejera, 1920

Trypanosoma rangeli is a species of hemoflagellate excavate parasites of the genus Trypanosoma. Although infecting a variety of mammalian species in a wide geographical area in Central and South America, this parasite is considered non-pathogenic to these hosts. T. rangeli is transmitted by bite of infected triatomine bugs of the Reduviidae family, commonly known as barbeiro, winchuka[1] (vinchuca), chinche, pito ou chupão.[2]

The genome was published in September 2014.[3]

Occurring in sympatry with Trypanosoma cruzi , the etiological agent of Chagas disease, in wide geographical areas in the Americas, T. rangeli shares hosts, vectors and a large amount of its antigenic coat T. cruzi leading to misdiagnosis of Chagas disease.[4][5]
