Nucleotide sequence of Korean isolates (SK) in the polymorphic region (corresponding to nt 3792 - 4029) of the PvGAM-1 gene, comparing with Belem strain, Chesson strain, and Sri Lankan isolates (K78.1, C164.3, C163.4, K156.1, C163.5. and K77.1) (Snewin et al., 1995). Gaps indicated by dashes (- - -) are introduced into the sequence to optimize the alignment. Dot marks the same nucleotide sequences with those of the first line, Belem strain. Bold and underlined italic type letters are repeat units (basically 33 bp), which consist of repeat 1, repeat 2, repeat 3 and repeat 4 in order. Except fourth truncated repeat (20 bp), the others are 33 bp in length.
