Anion-exchange separation for neotropical trypanosomes: a preliminary trial and a description of Trypanosoma devei from the tamarin Saguinus midas niger.

Anion-exchange separation trials using DEAE-cellulose columns were performed with blood from two single species of marsupial and edentate, three species of rodent and single species of carnivore, primate, cayman and lizard. Trypanosoma cruzi was isolated from Didelphis marsupialis, Dasypus novemcinctus and Coendou sp. T. (Megatrypanum) devei was isolated from the tamarin Saguinus midas niger and the mensural characters of the organism were redescribed. Anion-exchange separation was considered to be a valuable procedure for the taxonomist searching for new or little-known trypanosomes.
