Overview

  • Psychrobacter phenylpyruvicus, (aka Moraxella phenylpyruvica), 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 43%. Psychrobacter phenylpyruvicus is probably a rare gut coloniser. (Deschaght2012; Bowman1996; Snell1972)



  • This organism has been recovered from skin and mucous membranes. Also from clinical sources (blood, pus, cerebrospinal fluid, UTI). The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread. Can cause opportunistic infections, particularly in immunocompromised people. A possible gut commensal.
