aBased on the genotype of predominant T. cruzi clones and total number of alleles, as described (the section on ‘Materials and methods’).
bLineage assignation was performed using three different methods, as described (the section on ‘Materials and methods’). The nomenclature is according to Zingales et al. (2009): TcI (DTU I), TcII (DTU IIb), TcIII (DTU IIc), TcIV (DTU IIa), TcV (DTU IId) and TcVI (DTU IIe). Hybrid corresponds to TcV and TcVI (de Freitas et al., 2006).
