Parasitemia and survival of BALB/c mice infected with a lethal dose of T. cruzi and treated with DNA vaccines. Mice were infected with 5 × 104 T. cruzi parasites (strain H4) and treated on days 5 and 12 (arrows) with intramuscular injections of 100 μg of plasmid DNA encoding TSA-1 (•) or Tc24 (▴), control pcDNA3 plasmid (○), or a saline solution (□). (A and B) Infection monitored by measuring parasitemia. The values are means ± standard errors of the means for 3 to 15 mice per group. (C) Survival of infected and treated BALB/c mice.
