Overview

  • Bacillus niameyensis 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 37.40%. Bacillus niameyensis is probably a rare gut coloniser. (Alou2015a)



  • This organism has been recovered from human faeces (Alou2015a). Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
