  1. FREQUENCY OF NATURAL ANTIBODIES AND CONCORDANCE ANALYSIS FOR ANTI-TOXOPLASMA IgM TESTS IN COLOMBIAN SERA OF PREGNANT WOMEN

    • Diagnostic Microbiology and Infectious Disease

    • Interpretation of IgM anti-Toxoplasma can be problematic given the phenomena of “natural” IgM. We analyzed 1.503 sera obtained during prenatal care program, and we established natural and false-positive results by doing follow-up. In 101 samples the concordance between ELISA assay and two semi-automatized systems (Elecsys and VIDAS) was calculated.

  2. Toxoplasma gondii outbreak in southern Brazil: heterogeneity of the serological humoral response in pregnant women and outcomes in newborns

    • Diagnostic Microbiology and Infectious Disease

    • The aim of the study was to describe the heterogeneity of the humoral immune response and pregnancy outcomes in infected women during an outbreak of toxoplasmosis. Forty-two pregnant women referred to the University Hospital of Santa Maria (HUSM), RS, Brazil in 2018 and 2019, were evaluated. Clinical symptoms were reported in 33.3% of the patients. The majority (64.3%) of symptomatic pregnant women had anti T. gondii IgM antibodies index >7.0.
