Distribution of antibodies (anti-PfAMA-1 and anti-Pf113) concentrations according to the parasitemia. Plasma concentrations of malaria-specific antibodies were quantified in P. falciparum-infected Lastourville children. P. falciparum-infected children were subdivided into four groups based upon the parasite density. The very low density group was characterized by parasite density <1000 parasites/μl of blood. The low density group was defined by parasite density included between 1000 and 5000 para-sites/μl. Medium and high density groups were defined by parasite density included between 5000 and 10000 parasites/μl and >10,000 parasites/μl of blood, respectively
