Evaluation of immune responses induced by GRA7 and ROP2 genes by DNA vaccine cocktails against acute toxoplasmosis in BALB/c mice

ABSTRACT

Background: The severe damages of toxoplasmosis clearly indicate the need for the development of a more effective vaccine. Immunization with plasmid DNA is a promising vaccination technique. Therefore, GRA7 plasmid was prepared to be used as a vaccine. The purpose of this study was evaluation of immunization with cocktail DNA vaccine including plasmids encoding Toxoplasma gondii ROP2 and GRA7 in BALB/c mice
