Sumario:To perform IgG avidity immunoblotting assay for detection of acute toxoplasmosis, 100 serum samples were collected from Tehran, Iran. The presence of Toxoplasma-specific IgG and IgM antibodies were checked by commercial Trinity kit. Samples were categorized in acute and chronic phases of Toxoplasma gondii infection according to IgG avidity ELISA. IgG avidity immunoblotting was performed, and antigenic bands with molecular weights of 22, 25, 28, 30, 32, 42, 44, 49, 55, 60, 66, 69, 88, 106, 130 and 157 kDa were recognized as low avidity markers. The most prevalent antigen for low avidity was p22. It is concluded that IgG avidity immunoblotting could distinguish acute and chronic phases of T. gondii infection.
