Female BALB/cJ mice were infected with 500 trypomastigotes of T. cruzi VD strain; treatment started at 8 dpi and was administered orally for 20 consecutive days. * Results obtained from two independent assays.
Different letters indicate significant differences (Kruskal-Wallis; p < 0.05).
Values are expressed as mean (± standard deviation).
