FIG. 7.

Parasitemia levels and survival curve during the acute infection period in C3H mice infected with 5 × 10³ bloodstream trypomastigotes of T. cruzi. Mice were treated with psilostachyin or benznidazole from day 5 to 10 of infection. Parasitemia was determined by counting the number of trypomastigotes in 5 μl of fresh blood collected from the tail every other day (means ± SEMs). Mortality was recorded every day. The results presented are representative of three independent experiments.
