[Serodiagnosis of toxoplasmosis in man].

We want to repeat the interest of toxoplasmosis serodiagnostic in human pathology. First, to help the diagnostic of this affection, with adult and children; then, to prevent this parasitose with pregnant women. Results in our laboratory, since two years, point out that a large number of women are seronegative. We are proposing a protocol of supervision for women before and during their pregnancy. This protocol avoids the risk of foetal contamination and prevents congenital toxoplasmosis.
