Fig. 1. : Trypanosoma cruzi parasitism and inflammation persist in the heart tissue of chronically infected mice. A: experimental design of the article. C57BL/6 and C3H/He mice were infected with 100 blood trypomastigotes (bt) of the Colombian T. cruzi Type I strain and analysis at 70 days post-infection (dpi), 120 dpi or 150 dpi, according experimental protocol; B: kinetics of parasitaemia; C-D: quantitative data of the immunohistochemistry for T. cruzi parasite nests (C) and total inflammatory cells (D) in the heart tissue at 120 dpi; #: p < 0.05 C57BL/6 mice compared to C3H/He mice. Data obtained from three independent experiments [5 non-infected (NI) and eight-10 T. cruzi-infected mice per experiment].
