Survival curves of injected BALB/c mice against T. gondii challenge. The six groups of mice were challenged with 1 × 104 tachyzoites of virulent T. gondii RH strain 2 weeks after the last immunization. Each group was composed of ten mice and survival time was monitored daily for 18 days after challenge. * P < 0.05, as compared with PBS or pEGFP-C1; ** P < 0.05, as compared with pSAG1, pROM4 or peptide
