Fig. 2
In vitro P. falciparum susceptibility to multiple antimalarial drugs. Mean ± S.D IC50 values were calculated from 72-h dose–response assays for drugs designated in a–i. White bars represent standard laboratory-adapted clones, while blue and red bars indicate clinical-adapted parasites with PPQ sensitive or PPQ resistance, respectively. Three biological replicates were carried out for each sample. Statistically significant differences relative to isolate 17 are indicated with one (0.05 > p > 0.01) and two (p < 0.01) asterisks
