Overview

  • Helicobacter pullorum is a Gram-negative, non-spore-forming, microaerophilic, motile, helical-shaped bacterium. It has been detected in at least 8 gut microbiome compilation studies or metastudies. The DNA G+C content is 34-35%. Helicobacter pullorum is probably a common, although minor, coloniser of the gut. (Stanley1994; TrivettMoore1997; On2005Bergey; On2005Bergey)



  • This organism has been recovered from human faeces (diarrhoea), and animals. The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread (notes: human and animal pathogen). It is an opportunistic pathogen. A possible gut commensal.
