[Malaria in Gabon. Transplacental passage and dynamics of development of fluorescent antimalarial antibodies with age].

In permanent malaria transmission area (Gabon), fluorescent malarial antibodies have been studied among a population of mothers new borns and children from 1 to 15 years old. A lack of transplacental transfer of antibodies among african pairs "cord-mother" is noticed and in negative correlation with total mother IgG level. The antibodies rapidly increase from 1-2 years old still 9. Chimioprophylaxis does'nt modified for a long time the development of the FAT malarial antibodies.
