Abstract

We have assayed genetic polymorphisms in several species of parasitic protozoa by means of random amplified polymorphic DNA (RAPD). One goal was to ascertain the suitability of RAPD markers for investigating genetic and evolutionary problems, particularly in organisms, such as the parasitic protozoa, unsuitable for traditional methods of genetic analysis. Another goal was to test certain hypotheses concerning Trypanosoma cruzi, and other protozoa, that have been established by multilocus enzyme electrophoresis. The RAPD results corroborate the hypothesis that the population structure of T. cruzi is clonal and yield a phylogeny of the clonal lineages in agreement with the one obtained by enzyme electrophoresis. This parity between the two sets of results confirms that RAPD markers are reliable genetic markers. The RAPD markers are also suitable for reconstructing species phylogenies and as diagnostic characters of species and subspecific lineages. The number of DNA polymorphisms that can be detected by the RAPD method seems virtually unlimited, since the number of primers can be increased effectively at will. The RAPD method is well suited for investigating genetic and evolutionary questions in certain organisms, because it is cost effective and demands no previous genetic knowledge about the organism.
