Popis: | To study the usefulness of IgG and IgM titration, and avidity of IgG to date IgM anti-Toxoplasma gondii.VIDAS Toxo IgG, VIDAS Toxo IgM and VIDAS Toxo IgG Avidity tests were used. 64 sera containing both IgM and IgG T. gondii antibodies were analyzed, 32 from 12 individuals infected 40 weeks previously (group I), and the remainder from 17 individuals with an infection of more than 40 weeks (group II).An IgM index1.05 was associated with an infection12 weeks. An avidity index0.164 excluded 100% infections ofor = 12 weeks. Avidity indexes0.26 and 0.45 excluded infections ofor = 20 andor = 40 weeks, respectively.The serology methods used in this study can adequately identify residual IgM anti-T. gondii, often avoiding the need of a new blood extraction to analyze IgG kinetics in pregnant women. |
