Overview

  • Paludibacter propionicigenes is a Gram-negative, non-spore-forming, strictly anaerobic, non-motile, short rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 39.3%. Paludibacter propionicigenes is likely to be transient and not a long-term gut coloniser. (Ueki2006)



  • This organism has been recovered from plant residue, Japan. 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
  • Growth is poor at 33C or above, so unlikely to be a gut coloniser.
