Overview

  • Mycolicibacterium houstonense, (aka Mycobacterium houstonense), is a Gram-positive, non-spore-forming, microaerophilic, non-motile, pleiomorph rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 64%. Mycolicibacterium houstonense is probably a rare gut coloniser.



  • This organism has been recovered from face wound. 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. A possible gut commensal.
