Determination of specific anti-T. gondii IgG1 and IgG2a in immunized mice. The sera of 20 mice of each group were collected from 2 weeks after the final immunization and the IgG subtypes levels were analyzed by ELISA. T. gondii-specific IgG1 and IgG2a were used in the detection. Results are expressed as means of the OD490 ± SD statistically significant differences (p < 0.05) compared to the control groups. Each sample was tested three times. Compared with PBS or pEGFP-C1, p < 0.05 and ∗∗compared with pSAG4 or peptide, p < 0.05.
