INTRODUCTION: Genetic studies of Trypanosoma cruzi have tried to establish relations between genetic variants and their biological characteristics, such as clinical manifestations, host or geographic origin. However, much controversy exists on the associations between the commonly used DNA markers with group, clinical characteristics and disease epidemiology. OBJECTIVE: In this study determined the variability of the genes that code for the proteins trypanothione reductase and cruzipain, both involved in the infection and survival of the parasite in the mammalian host, was studied and the association between genetic polymorphism and biological and geographic sources in Colombian T. cruzi strains was examined. MATERIALS AND METHODS: The genotypes for each of six SNPs (single nucleotide polymorphisms) for trypanothione reductase and eight SNPs for cruzipain genes were identified by polymerase chain reaction-restriction fragment length polymorphism in 36 T. cruzi Colombian stocks from several regions and biological origins. RESULTS: Three genotypes were identified for trypanothione reductase with Acy I and Hae III enzymes and six genotypes for cruzipain with the Rsa I, Ban I and Bsu 361 enzymes. CONCLUSIONS: For trypanothione reductase, an association was not established with biological or geographical origin; however, alleles at positions 102 and 210 allowed discrimination with groups I and II. For cruzipain, specific genotypes were associated with group, biological and geographic origin. The usefulness of molecular markers on these genes was demonstrated for the determination and differentiation of genetic varieties in T. cruzi.
