| genetic structure and phylogenetic relationships of colombian trypanosoma cruzi populations as determined by schizodeme and isoenzyme markers. | twenty-four trypanosoma cruzi stocks isolated from vectors and from human and didelphis marsupialis hosts from highly separated sylvatic localities in colombia were characterized by isoenzyme and schizodeme analyses. the stocks were collected primarily from sylvatic ecotopes representing areas of low, moderate, and high endemicity for chagas' diseases in colombia. parasites were characterized mainly by schizodeme analysis with the restriction enzyme eco ri and the isoenzyme analysis was performe ... | 1999 | 10674683 |
