Toxoplasma-specific antibody levels in the sera of immunized BALB/c mice. The total IgG antibodies (a) in the collected serum samples of BALB/c mice immunized with pEGFP-SOD, pEGFP-C1, PBS and blank control on weeks 0, 2, 4, 8 were analyzed by ELISA. The levels of IgG1 and IgG2a (b) subtypes in the sera 28 days after the last immunization were determined by ELISA. The results are expressed as the means ± SD from three independent experiments. p < 0.05, pEGFP-SOD vs controls
