Overview

  • Arthrobacter parietis is a Gram-positive, non-spore-forming, aerobic, non-motile, bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 63.8%. Arthrobacter parietis is unlikely to be a gut coloniser. (Heyrman2005)



  • This organism has been recovered from a Roman tomb painting. 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
  • Doesn't grow well at 37C, so probably a gut transient organism.
