Overview


  • Arthrobacter citreus is a Gram-variable, non-spore-forming, strictly aerobic, variably-motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. Arthrobacter citreus is likely to be transient and not a long-term gut coloniser. (Sacks1954)



  • This organism has been recovered from chicken faeces. 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
  • Obligate aerobe; unlikely to be a gut coloniser.
