Trypanosoma species research and implications

SYNOPSIS. Previous attempts to dismember the genus Trypanosoma , by creating additional genera or subdividing it into subgenera, failed to gain acceptance, but, in the case of mammalian trypanosomes, the arrangement of species into informal groupings found more general recognition. However, as subordinate groups tend to multiply with advances in our knowledge, the classification of these trypanosomes threatens to become too unwieldy. It is therefore proposed to give assemblages of allied species a formal taxonomic status, by subdividing the genus Trypanosoma into subgenera, corresponding to previous minor groupings, but retaining the two major sections. The subgenera and their type‐species are as follows: A. Section STERCORARIA, with 4 subgenera: 1. Megatrypanum subgen.n.: Trypanosoma ( Megatrypanum ) theileri ; 2. Herpetosoma Doflein: Trypanosoma ( Herpetosoma ) lewisi ; 3. Schizotrypanum Chagas : Trypanosoma (Schizotrypanum ) cruzi ; 4. Endotrypanum Mesnil & Brimont: Trypanosoma ( Endotrypanum) schaudinni. B. Section SALIVARIA, with 4 subgenera: 5. Duttonella Chalmers: Trypanosoma (Duttonella) vivax ; 6. Nannomonas subgen.n.: Trypanosoma (Nannomonas ) congolense ; 7. Pycnomonas subgen.n.: Trypanosoma ( Pycnomonas ) suis ; 8. Trypanozoon Lühe: Trypanosoma (Trypanozoon ) brucei.
