title: The glycoproteins of the complex surface coat of Trypanosoma lewisi.
abstract: Blood stream forms of Trypanosoma lewisi from rats previously infected were labelled in vitro by galactose-oxidase oxidation followed by NaB3H4 reduction and subjected to 7.5% SDS-polyacrylamide gel analysis, by this procedure 8 bands were detected on SDS polyacrylamide gel electrophoresis. We conclude that surface composition of Trypanosoma lewisi resulted more complex than that of Trypanosoma so far studied, suggesting a possible relation with induced immunity and reduced ability of the parasite to survive in its host.
