This review focuses on the pathogenic significance of Helicobacterspecies naturally colonizing the stomach of dogs, cats and pigs. These gastric non-Helicobacter pylori Helicobacter species are less well-known than the human adapted H. pylori.

H. suis has been associated with gastritis and decreased daily weight gain in pigs. Several studies also attribute a role to this pathogen in the development of hyperkeratosis and ulceration of the pars oesophagea of the porcine stomach.

The stomach of dogs and cats can be colonized by several Helicobacterspecies but their pathogenic significance for these animals is probablylow.

H. suis as well as several canine and feline gastric Helicobacter species may also infect humans, resulting in gastritis, peptic and duodenal ulcers, and low-grade mucosa-associated lymphoid tissue lymphoma.
