Overview

  • Paenarthrobacter ilicis, (aka Arthrobacter ilicis), is a Gram-positive, non-spore-forming, aerobic, motile, rod-shaped-coccus cycle bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 61.5%. Paenarthrobacter ilicis is unlikely to be a gut coloniser. (Busse2016; Collins1981; Busse2012Bergey)



  • This organism has been recovered from blighted foliage of some trees. 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
  • Unlikely gut coloniser because this organism doesn't grow at 37C.
