ME49Δα‐amy vaccination prevented mice from the formation of cysts. The survived mice in both naïve and immunized groups challenged with TgPIG‐WH1 were sacrificed, and the number of Toxoplasma cysts in the brain was determined by DBA‐FITC staining under fluorescent microscopy. Data from the analysis of four mice in each group were graphed, *P < 0.05, Student’s t‐test.
