The description of very efficient system for production and purification of Toxoplasma gondii recombinant antigens, GRA6, p35 and SAG2 is given in this study. The usefulness of these antigens for diagnostic of human infections was tested in an ELISA using 99 sera obtained during routine diagnostics. The sera for testing were selected from either acute or chronically infected patients. Both r-GRA6 and r-p35 antigens detected antibodies more frequently (p<0.01) from acute (93.9 and 87.9%) rather than chronic (60.6 and 53.0%) infections. The r-SAG2 gave a similar sensitivity in both groups of patients (93.9 and 95.5%).
