L’objectif global de ce protocole est de fournir des instructions sur la façon de mesurer la capacité des anticorps présents dans les sérums ou le plasma des individus, naturellement exposés à l’infection de Plasmodium falciparum, d’opsoniser et d’induire la phagocytose des érythrocytes infectés par le parasite (EI).
