Overview

  • Pseudomonas protegens is a Gram-negative, non-spore-forming, strictly aerobic, non-motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 60.1-63.3%. Pseudomonas protegens is likely to be transient and not a long-term gut coloniser. (Ramette2011)



  • This organism has been recovered from soil and plant roots. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Strictly aerobic and reduced growth at 37C suggests this is unlikely to be a gut coloniser.
    • GENERAL CHARACTERISTICS (Ramette2011);
    Character Response
