Overview

  • Pedobacter terricola is a Gram-negative, non-spore-forming, aerobic, non-motile, pleiomorph rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 36.8%. Pedobacter terricola is unlikely to be a gut coloniser. (Yoon2007; Zhou2012a)



  • This organism has been recovered from island soil, Korea. 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
  • Not likely to be a gut coloniser because this organism doesn't grow at 37C.
