Polio type 2 and 3 eradication: Relevance to the immunity status of individuals living in Germany, 2005-2020.

Since October 2019, poliovirus type 3 (PV3) has been certified as globally eradicated, and further laboratory use of PV3 will be restricted according to the WHO Polio Eradication Initiative and containment measures. To examine a possible gap in PV3 immunity and a lack of immunity against poliovirus type 2 (PV2), which was already declared as eradicated in 2015, neutralising antibodies against polioviruses (PV) of individuals living in Germany (n = 91,530 samples; mainly outpatients (≈90%) who received immune status testing) were investigated from 2005 to 2020 (age distribution: <18 years 15.8%, 18-64 years 71.

Sulfadiazine plasma concentrations in women with pregnancy-acquired compared to ocular toxoplasmosis under pyrimethamine and sulfadiazine therapy: a case-control study.

Background: Dosing recommendations for the treatment of pregnancy-acquired toxoplasmosis are empirical and widely based on experimental data. There are no pharmacological data on pregnant women with acute Toxoplasma gondii infection under treatment with pyrimethamine (PY) and sulfadiazine (SA) and our study intends to tighten this gap.

Methods: In this retrospective case-control study, we included 89 pregnant women with primary Toxoplasma infection (PT) treated with PY (50 mg first dose, then 25 mg/day), SA (50 mg/kg of body weight/day), and folinic acid (10-15 mg per week).

Evaluation of a commercial IgG/IgM Western blot assay for early postnatal diagnosis of congenital toxoplasmosis.

The aim of this study was to evaluate a commercial Western blot IgG/IgM assay for use in the early serological diagnosis of congenital toxoplasmosis. This assay compares the immunological profile of mother and infant and allows differentiation between passive transmitted maternal antibodies and newly synthesized antibodies of the infant within the first 3 months of life. Over a 6-year period (1995-2001), the sera from 169 mothers and their 175 offspring (6 had twins) were examined for specific anti- Toxoplasma gondii IgG, IgM and IgA antibodies with an enzyme-linked immunosorbent assay or an immunosorbent agglutination assay.
