Overview

  • Flavobacterium oncorhynchi is a Gram-negative, non-spore-forming, 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 33.0%. Flavobacterium oncorhynchi is likely to be transient and not a long-term gut coloniser. (Zamora2012)



  • This organism has been recovered from human faeces, and rainbow trout. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Can't grow at 37C, so unlikely to be a gut coloniser.
