Figure 2
Total IgG titers in T. cruzi-infected dogs treated with plasmid DNA. ELISA was performed at different times to evaluate the serum levels (absorbance in optical density at 405 nm) of T. cruzi IgG-specific antibodies. Preinfection; post 2nd treatment: 45 days after infection and 15 days after the second immunotherapy; and post 3rd treatment: 60 days after infection and 15 days after the third immunotherapy. The values represent the . Significant differences () were not identified.
