Overview

  • Myroides odoratimimus, (aka Flavobacterium odoratum), is a Gram-negative, non-spore-forming, strictly aerobic, non-motile, rod-shaped bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 30-35%. Myroides odoratimimus is likely to be transient and not a long-term gut coloniser. (Vancanneyt1996)



  • This organism has been recovered from clinical sources (wound, urine, pus) and water. The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread. It is an opportunistic pathogen. Likely to be transient and not a long-term gut commensal.
