Overview

  • Paraburkholderia phytofirmans, (aka Burkholderia phytofirmans), is a Gram-negative, non-spore-forming, facultatively anaerobic, motile, rod-shaped bacterium. The DNA G+C content is 61.0-62.1%. Paraburkholderia phytofirmans is likely to be transient and not a long-term gut coloniser. (Sessitsch2005)



  • This organism has been recovered from onion roots, Canada. The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Inability to grow at 37C suggests this is unlikely to be a gut coloniser.
