Fig. 1

Geographic distribution of the pvmdr1 haplotypes. The graphic was made using 550 samples collected in the Northern Amazon Basin (n = 445), the Southern Amazon Basin (n = 48) and the North Coast (n = 57). Pie charts indicate the pvmdr1 haplotype present in a region and their prevalence. The M908L/T958M haplotype was distributed in all sites while the T958M/F1076L haplotype was specific for the North Coast
