Polymorphisms in the repetitive domain of Plasmodium vivax dihydropteroate synthase. Deletions are denoted by dashes. RH1–RH6 are from this study. A*–H* correspond to the alleles described by Hawkins and others,³² and A′–D′ represent the alleles from Menegons and others. ²⁶ Sequences were aligned with the Sal I reference sequence (www.tigr.org), and the repeat units are labeled consecutively as R1 through R13. The frequency of each allele identified in this study is shown as number (N) and percentage (%).
