Overview

  • Bacillus rubiinfantis is a Gram-positive, spore-forming, facultatively anaerobic, motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 40.0%. Bacillus rubiinfantis is probably a rare gut coloniser. (Alou2015)



  • This organism has been recovered from human faeces (Alou2015). Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
