Overview

  • Erwinia tasmaniensis is a Gram-negative, non-spore-forming, facultatively anaerobic, motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 50.5-52.4%. Erwinia tasmaniensis is likely to be transient and not a long-term gut coloniser.



  • This organism has been recovered from apple and pear trees, Australia. 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 36C suggests this not a gut coloniser.
