Worldwide prevalence of Sudanese pvdbpII haplotypes. The frequencies of 8 haplotypes based on 10 common non-synonymous polymorphic sites (Additional file 2) are depicted as pie charts and mapped to their geographic origin. Coloured segments indicate shared haplotypes with Sudan (dark blue = Haplotype 1, Sudan n = 11, Brazil n = 8, Iran n = 2, South Korea n = 5, Sri Lanka n = 2, Thai n = 1; bright green = Haplotype 2, Sudan n = 7, Brazil n = 2, Sri Lanka = 1, India n = 1; red = Haplotype 3, 5, 11 Sudan n = 12, Iran n = 1, PNG n = 1, Sri Lanka n = 6, Thai n = 1, India n = 7, Myanmar n = 1; Gold = Haplotype 4, Sudan n = 5, PNG n = 1, India n = 1; purple = Haplotype 6, 10 Sudan n = 4, Brazil n = 23, Iran n = 2, Sri Lanka n = 44, Thai n = 1, India n = 29; orange = Haplotype 7, Sudan n = 1, Brazil n = 18, Colombia n = 1, Sri Lanka n = 3, Thai n = 2, India n = 12, Myanmar n = 2; n = 1 and pink = Haplotype 8, Sudan n = 1, India n = 7; brown = Haplotype 9 Sudan n = 1 South Korea n = 1; Sri Lanka n = 1) and grey indicates other haplotypes to respective population. Note that haplotypes 5 and 11, and 10 correspond to haplotypes 3 and 6, respectively, because 10 non-synonymous SNPs out of 14 non-synonymous SNPs (Fig. 1a) were considered in this analysis
