Figure 1: Parasitemia and Survival curve in mice infected with T. cruzi BT. Mice were inoculated ip with 1 × 1 0 4 BT Ninoa () or Qro () strains. (a) Parasite number in blood was determined by counting in a Neubauer chamber using an optic microscopy. Statistical differences in blood parasite number are indicated ( 𝑃 < . 0 5 ) at 25 y 29 days post infection. (b) Survival of mice infected with T. cruzi strains was evaluated using groups of 28 mice infected with T. cruzi strains. Daily direct observation was done and dead mice were recorded.
