[Cohorts and bio-libraries for studying malaria in tropical areas].
The relationship between Plasmodii transmission, infection, morbidity, genetic susceptibility and acquisition of natural immunity is studied among two cohorts in the Senegalese villages of Dielmo (300 inhabitants) and Ndiop (350 inhabitants) where malaria is holoendemic (about 200 P. falciparum infective bites/person/year) and mesoendemic (about 20 P. falciparum infective bites/person/year), respectively. The populations are under a daily active clinical survey. Blood samples are collected at least once per month. Plasma and red blood cells are stored in bio-libraries that allow longitudinal studies of the immune responses against plasmodial antigens and the investigation of the natural history of P. falciparum infections by molecular genotyping methods.
