Overview

  • Helicobacter pametensis is a Gram-negative, non-spore-forming, microaerophilic, motile, rod-shaped - curved bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 38%. Helicobacter pametensis is probably a rare gut coloniser. (Dewhirst1994)



  • This organism has been recovered from bird faeces. The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread. Could be a possible pathogen in humans, but unknown at this stage. A possible gut commensal.
