Overview


  • Hungatella effluvii is a Gram-positive, spore-forming, strictly anaerobic, motile, rod-shaped bacterium. It has been detected in at least 3 gut microbiome compilation studies or metastudies. The DNA G+C content is 51.4%. Hungatella effluvii is probably a common, although minor, coloniser of the gut. (Kaur2014)



  • This organism has been recovered from human faeces (Alkhalil2017) and anaerobic digester. Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.

  • QUIRKS
  • In 65% of Europeans (unseenbio.com). Minor coloniser.
