Figure 6From: Influence of oxygen on asexual blood cycle and susceptibility of Plasmodium falciparum to chloroquine: requirement of a standardized in vitro assayChemosusceptibility of Plasmodium falciparum isolates to chloroquine under 10% O 2 and 21% O 2 . A: chloroquine IC50 of 120 isolates. B: red plots corresponds to isolates with a switch from susceptible to chloroquine at 10% O2 to resistant at 21% O2; blue plots corresponds to isolates with a switch from resistant at 10% O2 to susceptible at 21% O2.Back to article page
