Overview

  • Halobacteroides halobius is a Gram-negative, non-spore-forming, strictly 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 30.7%. Halobacteroides halobius is likely to be transient and not a long-term gut coloniser. (Oren1984)



  • This organism has been recovered from Dead Sea sediment. 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. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Very high salt concentration requirement makes this an unlikely gut coloniser.
