Overview

  • Pseudomonas libanensis is a Gram-negative, non-spore-forming, aerobic, motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 58%. Pseudomonas libanensis is unlikely to be a gut coloniser. (Palleroni2005bBergey; Dabboussi1999)



  • This organism has been recovered from spring water, Lebanon. 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.
