Alignment of nucleotide sequences of 16S rRNA genes from four clinical isolates (K96243, K94050, S94004, and S94017) and five soil isolates (TRF684, TRF685, TRF688, TRF824, and TRF830) of Ara− B. pseudomallei, and one clinical isolate (S95019) and four soil isolates (TRF681, TRF682, TRF683, and TRF686) of Ara+ B. pseudomallei (GenBank accession no. AF093047 to AF093060). The published sequences of B. pseudomallei 1026b (U91839) and B. thailandensis E264 (U91838) are also included for comparison.
