Overview

  • Mycobacterium kansasii is a Gram-variable, non-spore-forming, aerobic, non-motile, rod-shaped bacterium. It has been detected in at least 3 gut microbiome compilation studies or metastudies. Mycobacterium kansasii is likely to be transient and not a long-term gut coloniser. (Magee2012Bergey)



  • This organism has been recovered from pulmonary legions. 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.
