[Toxoplasmosis in pregnant women in Haut Ogooué Province (Gabon)].

Anti-toxoplasma antibodies have been studied in 268 pregnant women. Two serological tests have been used: direct agglutination, before and after treatment with 2-mercaptoethanol, and indirect immunofluorescence. Agreement between the tests is over 98%. 60.5% of women have anti-toxoplasma antibodies at first examination. This percentage remains unchanged during pregnancy. Two cases of evolving toxoplasmosis have been observed. The mode of infection in Gabon is discussed.
