Fig. 4From: Influence of the sickle cell trait on Plasmodium falciparum infectivity from naturally infected gametocyte carriersMosquito infection burden according to gametocytemia in HbAA and HbAS blood donors. The relationship between gametocyte density of the blood donor and oocyst intensity was assessed for HbAA (green) and HbAS (orange) individuals. The difference in oocyst loads between mosquitoes fed on HbAA and HbAS blood increased with gametocyte densities but did not reach significant level (Wald test, P = 0.318)Back to article page
