Overview

  • Ornithinibacillus contaminans is a Gram-positive, spore-forming, strictly aerobic, non-motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. Ornithinibacillus contaminans is likely to be transient and not a long-term gut coloniser. (kampfer2010)



  • This organism has been recovered from a blood sample. Can cause opportunistic infections, particularly in immunocompromised people. Likely to be transient and not a long-term gut commensal.
