Overview

  • Streptomyces thermoviolaceus is a Gram-positive, exosporous, aerobic, non-motile, filamentous bacterium. It has been detected in at least 3 gut microbiome compilation studies or metastudies. Streptomyces thermoviolaceus is probably a rare gut coloniser. (Kim1999)



  • This organism has been recovered from human faeces (Hoyles2012) and blood. 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. A possible gut commensal.
