Abstract

Genes encoding for the KMP-11 protein were localized on the chromosomes of Trypanosoma rangeli. These genes were located in two chromosomes of 3,100 and 3,400 kb in the KP1(-) strain whereas in the KP1(+) H14 and Choachí strains, the genes are located in a chromosome of 1,600 kb. The Choachí strain presents an additional band of 1,400 kb. In the Shubacbarina and Munanta strains of Trypanosoma cruzi, the KMP-11 genes are located on a chromosomal band of 1,490 kb. Therefore, the chromosomal localization of the KMP-11 genes presents a potential tool to differentiate among these parasites.
