This study describes the isolation and characterization of several Burkholderia species from soil in northern Australia. Phenotypic and molecular tests indicate that these isolates belong to the species Burkholderia thailandensis and Burkholderia ubonensis. These observations significantly extend our knowledge of the geographic distribution of these 2 species. Evidence of these species in Australia has implications for bacterial identification in clinical laboratories, diagnostic serology tests, and environmental biodiversity studies.
Received November 9, 2007. Accepted for publication January 26, 2008.
Acknowledgments: We thank Vanaporn Wuthiekanun for kindly supplying the B. thailandensis strains used for comparison purposes. The authors thank Tim Reid at The Naval Medical Research Center Annex, Rockville, MD, for sequencing the B. thailandensis and B. ubonensis genomes. We also appreciate the advice offered by Steve Munyard in phenotypic characterization of isolates and Lyn OReilly in pulsed-field gel electrophoresis.
