Overview

  • Chryseobacterium indologenes, (aka Flavobacterium indologenes), is a Gram-negative, non-spore-forming, facultatively anaerobic, 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 37.3-38.3%. Chryseobacterium indologenes is probably a rare gut coloniser. (Yabuuchi1983)



  • This organism has been recovered from clinical sources (sputum, pus, urine, pharynx). The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread (notes: human and animal pathogen). Is a known human pathogen. A possible gut commensal.
