Determination of diagnostic value of Toxoplasma gondii recombinant surface antigen (SAG1, P30) in mouse experimental model

The aim of this study was to test the potential diagnostic usefulness of recombinant Toxoplasma gondii SAG1 antigen and excretory-secretory antigen (ESA), with respect to toxoplasmosis detection and infection phase distinction in laboratory mouse by determining specifi c serum IgM and IgG antibodies...
