Abstract

Thirty six stocks of isolated from sylvatic mammals (32 and one ) and triatomine bugs ( and one unidentified bug) in the Amazonian forest of Carajas, Brazil were characterized by isoenzyme and random amplified polymorphic DNA (RAPD) analysis as belonging to principal zymodeme 1 (Z1). Two different homozygous phenotypes and the corresponding heterozygous phenotype were found for phosphoglucomutase with an observed frequency almost identical with that predicted by the theoretical Hardy-Weinberg distribution. Parental and hybrid profiles were also suggested by RAPD analysis, which allowed exclusion of mixed parental strains from the hybrids: isoenzyme and RAPD profiles of biological clones were also indistinguishable from those of uncloned stocks. stocks from widely separated geographic origins in Central and South America gave similar RAPD profiles that allowed them to be recognized as being Z1. These results indicate that genetic exchange could contribute to the generation of genetic diversity during the sylvatic cycle of , and this may have epidemiologic and taxonomic implications.
