Overview

  • Pseudomonas gessardii is a Gram-negative, non-spore-forming, aerobic, motile, rod-shaped bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 58%. Pseudomonas gessardii is unlikely to be a gut coloniser. (Palleroni2005bBergey; Verhille1999; vandenBeld2016)



  • This organism has been recovered from natural mineral waters. 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.
