Overview

  • Streptomyces violaceusniger is a Gram-positive, exosporous, aerobic, non-motile, filamentous bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 71.2%. Streptomyces violaceusniger is likely to be transient and not a long-term gut coloniser. (Kampfer2012Bergey; Labeda1991)



  • This organism has been recovered from sources unknown. The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Streptomyces, being aerobic and having lower optimum growth temperatures are unlikely to be gut colonisers.
