A The effect of 50 μM 2-Meotio on the interaction between peritoneal macrophages and parental or resistant lines of T. cruzi (Y strain) for 24 h. a, b Parental line untreated and treated with 2-Meotio. c, d M15 line untreated and treated with 2-Meotio. Magnification ×40. B Endocytic Index (the percentage of infected cells versus the number of intracellular amastigotes) for the treatment of T. cruzi with 2-Meotio. C The effect of 50 μM benznidazole (Bz) on the interaction of peritoneal macrophages with parental or resistant lines of T. cruzi (Y strain) for 24 h. a, b Parental line untreated and treated with Bz. c, d B15 line untreated and treated with Bz. Magnification ×40. D Endocytic Index for the treatment of T. cruzi with Bz for 24 h. Asterisk, significant difference in the parental line when comparing the endocytic index in the treated group versus the control
