摘要：

A difficulty when detecting both anti-Toxoplasma gondii-specific IgG and IgM in pregnant women is estimating the date of infection. The aim of this study was to compare the anti-Toxoplasma-specific immunoglobulin kinetics of 7 serological techniques to date the infection and to draw kinetic curves that are easy to use on a daily basis. IgG and IgM antibodies were measured on 691 sera samples. IgM appeared a few days, less than 1 week, after the beginning of the infection. Then, the levels of IgM reached a peak at approximately 3, 4, and 5 weeks with Toxo-ISAGA (R) IgM, IgM homemade indirect immunofluorescence assays, and Vidas Toxo (R) IgM, respectively. Furthermore, the Architect Toxo (R) IgG titers were higher than those of the Vidas Toxo (R) IgG results in recent infection (less than 6 months). This study provides new average IgM and IgG curves that can help to determine the approximate date of infection. (C) 2020 Elsevier Inc. All rights reserved.
