a Schematic diagram of Plasmodium knowlesi merozoite surface protein 1 (PkMSP1) domain wise nucleotide diversity within 11 Malaysian isolates. b Alignment of 11 pkmsp1 isolates from Malaysia indicating the four variable domains (II, IV, VI and VIII) and conserved domains (I, III, V, VII and IX) based on Putaporntip et al. [39]. Sequence identity within the isolates are shown in dark green, SNPs as light green and alignment gaps were shown as white
