Overview

  • Bacteroides neonati is a Gram-negative, non-spore-forming, strictly anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 4 gut microbiome compilation studies or metastudies. The DNA G+C content is 43.5%. Bacteroides neonati is probably a common, although minor, coloniser of the gut. (Cassir2014)



  • This organism has been recovered from human faeces (neonate stool - Cassir2014). Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
    • QUIRKS
  • In 63% of Europeans (unseenbio.com). Minor coloniser.
