Characterization of stocks of Trypanosoma vivax

Abstract

Nine Trypanosoma vivax stocks were compared on the basis of their isoenzyme patterns for 12 enzymes by means of thin-layer starch gel and polyacrylamide gel electrophoresis.

Malic enzyme showed the greatest variation and two distinct band patterns were observed. Of the other enzymes investigated all stocks showed identical electrophoretic mobility except a rodent-adapted stock of T. vivax which differed in two enzymes.

There was no enzymic division between T. vivax stocks of African origin and a stock of South American origin.
