Overview

  • Bacillus mediterraneensis, (aka Bacillus massilionigeriensis), 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 42.3%. Bacillus mediterraneensis is probably a rare gut coloniser. (Cadoret2017; Alou2016e)



  • This organism has been recovered from the faeces (Cadoret2017) of a healthy child, Senegal. Pathogenicity status unknown, or very unlikely to be pathogenic. Is a known gut commensal.
    • QUIRKS
  • May be able to persist in the gut, albeit in low numbers, by residing in niches close to epithelial cells (Ilinskaya2017).
    • GENERAL CHARACTERISTICS (Cadoret2017);
    Character Response
  • Substrates hydrolysed or digested:
  • gelatin;
  • 🌡
  • Temperature tolerance:
  • Grows optimally at 37℃.
  • H+
  • Acid from carbohydrates usually produced:
  • L-arabinose; fructose; glucose; mannose; ribose; xylose; cellubiose; maltose; melezitose; sucrose; trehalose; D-arabitol; mannitol; sorbitol; arbutin; gluconate; 5-ketogluconate; N-Ac glucosamine; salicin;
  • Active enzymes:
  • naphthol-ASBI-P;
    • SPECIAL FEATURES (Cadoret2017);
    Character Response
  • ✗
  • Nitrate:
  • not reduced
    • RESPONSE TO ANTIBIOTICS (Cadoret2017);
    Class Active Resistant
  • Penicillins:
  • amoxicillin; imipenem; penicillin G;
  • Tetracyclines:
  • minocycline;
  • Vancomycins:
  • vancomycin;
