Overview

  • Mycobacterium tuberculosis variant bovis, (aka Mycobacterium bovis), is a Gram-positive, non-spore-forming, microaerophilic, 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 65.6%. Mycobacterium tuberculosis variant bovis is likely to be transient and not a long-term gut coloniser. (Magee2012Bergey)



  • This organism has been recovered from tuberculosis in cattle, man and other animals. The risk classification (www.baua.de) for this organism is 3, i.e., high risk of individual infection, and some risk of spread (notes: vaccine available, zoonotic pathogen). This is a dangerous pathogen. A possible gut commensal.
    • QUIRKS
  • Pathogenic; unlikely to be a coloniser in a healthy microbiome.
