Overview

  • Spiribacter roseus is a Gram-negative, non-spore-forming, strictly aerobic, non-motile, rod-shaped - curved bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 64.2%. Spiribacter roseus is unlikely to be a gut coloniser. (Leon2016)



  • This organism has been recovered from pond water, Spain. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Strict aerobe and high optimum salt concentration suggests this organism is likely to be a gut non-coloniser.
