Overview

  • Metabacillus galliciensis, (aka Bacillus galliciensis), is a Gram-positive, spore-forming, aerobic, motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 48.1%. Metabacillus galliciensis is likely to be transient and not a long-term gut coloniser. (Balcazar2010)



  • This organism has been recovered from human faeces and seahorse faeces. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Optimum growth temp is low (20C), so unlikely to be a gut coloniser.
