Toxoplasma gondii, the pathogen of toxoplasmosis, can infect most mammals and birds. The high incidence and severe or lethal damages of toxoplasmosis clearly indicate the need for the development of a more effective vaccine. We constructed a DNA cocktail, containing plasmids encoding the full-length SAG1 and ROP2 genes of T. gondii and evaluated its immune response and protective efficacy in comparison with single-gene vaccines and control groups. We immunized BALB/c mice intramuscularly three times. DNA cocktail elicited IgG and IFN-gamma, TNF-alpha and IL-2 greater than single-gene plasmi…
