Molecular characterization of Mexican stocks of Trypanosoma cruzi using total DNA.

The American journal of tropical medicine and hygiene - 1 Aug 1992

Zavala-Castro J E, Velasco-Castrejon O, Hernandez R

Abstract excerpt

Seventeen Mexican Trypanosoma cruzi stocks and five South American reference strains were analyzed by Hind III restriction fragment length polymorphisms associated with ribosomal RNA gene spacers and by HinfI digestion patterns of total DNA. Our findings demonstrate the occurrence of genetic heterogeneity within these stocks. Hierarchic and non-hierarchic clustering of these molecular characters allowed the...
