Overview

  • Streptomyces albus is a Gram-positive, exosporous, aerobic, non-motile, filamentous bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. Streptomyces albus is likely to be transient and not a long-term gut coloniser. (Labeda2014; Martin2004)



  • This organism has been recovered from human faeces, clinical specimens and the environment. The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread. Could be a possible pathogen in humans, but unknown at this stage. Likely to be transient and not a long-term gut commensal.
