Helicobacter canis is a gram negative bacterium in the Helicobacteraceae family, Campylobacterales order.[1] It was first identified and isolated from dog feces, though sheep and cats may also be important reservoirs of the bacterium.[2] Its type strain is NCTC 12739T. It colonises the lower bowel, but is also present in cases of hepatitis.[3] Besides infecting dogs, this bacterium is known to cause infections in immunocompromised humans.[4][5]

Description
editCells of H. canis are spiral, sometimes with truncated ends. Flagella are single and bipolar, as well as sheathed, a characteristic of genus Helicobacter, and connected to a basal plate at their insertion into the cell.[1]
Epidemiology
editH. canis infections have been identified globally in human and animal populations, including in Europe, South America, and Asia.[6] The precise route of transmission is not well understood, though infections may spread through contact with saliva, vomit, and contaminated food or water.[6] Other potential risks of indirect spread include exposure to domesticated dogs and cats.
