Toxoplasmic lymphadenitis--clinical and serologic profile.

Objective: To study the serologic profile of several types of test for toxoplasmosis, in order to contribute to the interpretation of antibody kinetics.

Methods: The clinical and serologic features of 120 cases of lymphadenopathy with known time of clinical onset were studied during 18 months postinfection. Antibody kinetics was determined by Sabin-Feldman dye test, complement fixation with light antigen, IgM immunofluorescent antibody test, and IgM immunosorbent agglutination assay (IgM-ISAGA).
