Morphological and Taxonomic Studies on Mammalian Trypanosomes

Abstract

This paper is devoted to a critical analysis and revision of the systematics of the mammalian trypanosomes. It is shown that there is no justification for the recognition of more than one genus, Trypanosoma.The trypanosomes are subdivided into two sections, each with distinct morphological and biological characteristics.In the section corresponding to the lewisi group the method of reproduction is used as a criterion for the specific differentiation of the trypanosomes.
