摘要: The question of whether any sexual process takes place at some stage the life cycle trypanosome has often been raised and crosses between different drug-resistant strains have provided no convincing answer. Multinucleate forms trypanosomes observed by electron microscopy but their significance origin remain obscure. As part a study aimed examining speciation genetics Trypanosoma brucei complex trypanosomes, series isolates from population T.b. screened for electrophoretic variation in 19 enzymes. results this survey, reported here, provide strong evidence that are diploid undergo random mating recombination.
