Overview

  • Helicobacter canis is a Gram-negative, non-spore-forming, microaerophilic, motile, helical-shaped bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 48.2-48.8%. Helicobacter canis is likely to be transient and not a long-term gut coloniser. (On2005Bergey; Stanley1993)



  • This organism has been recovered from human faeces (diarrhoea), blood, and dogs. 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. Likely to be transient and not a long-term gut commensal.
