Phylogenetic tree based on the concatenation of cox1 and GPI sequences. The concatenated data show a clear separation between T. cruzi DTUs TcI, TcII, TcIII and TcIV, Tcbat, T. c. marinkellei, T. dionisii and T. rangeli. The heterozygous hybrids TcV and TcVI were not differentiated from each other. The numbers at the nodes correspond to NJ, ML, MP and BI support values, respectively (only values >60 are shown). The scale-bar shows the number of nucleotide substitutions per site
