FIG 5.

Microsatellite haplotype profiles (H1 to H31) on four loci flanking dhfr in isolates from southern China. Each box represents the microsatellite type at codons 16, 51, 59, 108, and 164 of each pfdhfr allele in the six sampling sites. Identical colors (green and blue) represent proposed common lineages. Blue grids represent the SEA lineage, whereas the HN lineage is shown in green. The yellow grids under the column “Haplotypes” indicate a hybrid of the SEA and HN haplotypes based on microsatellite characteristics at loci −3.87, −0.1, and 5.87. The numbers under the column “Region” indicate the frequency of each haplotype in various regions. LZ, Lazan; TC, Tengchong; DH, Dehong; DF, Dongfang; LeD, Ledong; SY, Sanya.
