Figure 2.

Prevalence of antimalarial drug resistance-associated single nucleotide polymorphisms (SNPs): Each bar represents the proportion of the samples that display the mutant (blue) or wild-type (orange) amino acid at the position designated below the bar. Besides Plasmodium falciparum chloroquine resistance transporter (pfcrt)-76 and P. falciparum multidrug resistance gene one (Pfmdr1)-86 with mutations less than 10%, all other SNPs that we investigated were found to be saturated. No mutation in dhps-540 was found. This figure appears in color at www.ajtmh.org.
