Overview

  • Flavobacterium cheniae is a Gram-negative, non-spore-forming, aerobic, gliding, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 40.6%. Flavobacterium cheniae is probably a rare gut coloniser. (Joung2013; Qu2008)



  • This organism has been recovered from human faeces, and polluted waters. Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
