Unknown in 1980, suspected in 1983 and scarcely present in 1984-85, Plasmodium falciparum resistance to chloroquine as studied in vivo in schoolchildren in Gabon, has strongly developed in 4 years time. In 1987-88, administration of 25 mg/kg of chloroquine leaves one strain out of four with a parasitic load greater than 10/1.000 red blood cells examined by(More)
During the last 25 years, 64 cases of chromoblastomycosis were diagnosed in Gabon. They came from the entire territory, where living in rural zones men as well as women were affected.

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(More)
