Overview

  • Janibacter terrae is a Gram-positive, non-spore-forming, aerobic, non-motile, coccus bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 69%. Janibacter terrae is probably a rare gut coloniser. (Yoon2000)



  • This organism has been recovered from human faeces, blood and wastewater. 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.
