Diagnostic value of tests for Toxoplasma gondii-specific antibodies in patients undergoing bone marrow transplantation.

The value of Toxoplasma gondii-specific antibodies for the diagnosis of reactivated toxoplasmosis in immunocompromised patients is controversely discussed. The present study was performed to investigate the value of testing for antibodies against Toxoplasma gondii in patients undergoing bone marrow transplantation (BMT). Of 75 patients enrolled in the study, 53 (70.

Comparison of two commercially available avidity tests for toxoplasma-specific IgG antibodies.

Background: IgG anti-Toxoplasma avidity tests have proven useful to discriminate between recent and distant infection in management of pregnant women with anti-Toxoplasma-IgM antibodies. This study was performed to compare two commercially available IgG anti-Toxoplasma avidity test kits.

Methods: Sixty-four samples positive for IgM and IgG anti-Toxoplasma antibodies were analyzed with two IgG anti-Toxoplasma avidity tests: VIDAS Toxo IgG avidity kit (BioMérieux, Marcy-l'Etoile, France) and Toxoplasma gondii IgG avidity EIA kit (Labsystems, Helsinki, Finland).
