Sequential recognition of antigenic markers of Toxoplasma gondii tachyzoite by pooled sera of mice with experimental toxoplasmosis.

Accurate diagnosis of maternal toxoplasmosis can enhance the success of medical treatment and prevent congenital transmission. The current diagnostic methods have many limits, and they poorly differentiate between recent and latent infections. The present work was conducted to record the sequential recognition of antigenic markers of both Toxoplasma tachyzoites whole extract and glycosylinositolphospholipids (GIPLs)-enriched fraction by specific IgG and IgM, respectively, by immunoblotting analysis of the antigens against daily pooled serum samples from mice with experimentally induced recent and latent toxoplasmosis.
