Modulation of immune response in experimental Chagas disease

Figure 4 Specific IgG isotype levels in peritoneal fluid obtained from vaccinated, (light gray bars) or control mice, (dark gray bars) before and after infection determined by enzyme-linked immunosorbent assay (optical density mean ± SE). The doted line is the parasitemia level at different time of infection. Significant differences between both groups evaluated by Student’s t-test (^aP < 0.05, ^bP < 0.001).
