FIG. 1.

Variable sites within the alleles at the seven MLST loci. The sequences of all of the alleles at each locus that are represented among the 147 Burkholderia isolates are shown. Only the variable sites are shown, and these are numbered in vertical format. For allele 1 at each locus, the nucleotide present at each variable site is shown. For other alleles, only those sites where the nucleotides differ from those in allele 1 are shown; sites that have the same nucleotide as that in allele 1 are shown by a dot. The alleles in normal font are from B. pseudomallei, those in boldface are from B. thailandensis, and the final allele at each locus (in italics) is from the Oklahoma isolates.
