Overview

  • Halopseudomonas pelagia, (aka Pseudomonas pelagia), is a Gram-negative, non-spore-forming, strictly 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 59.1%. Halopseudomonas pelagia is likely to be transient and not a long-term gut coloniser. (Hwang2009)



  • This organism has been recovered from green alga, Antarctic. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Low optimum temperatures (25C) and strictly aerobic requirements makes this a very unlikely gut coloniser.
