“…There is evidence that a number of gastric Helicobacter spp. can be transferred from dogs [73], as it was shown from cats [74], to their owners. In larger series Candidatus H. suis, H. felis, H. bizzozeronii, H. salomonis, Candidatus H. bovis, as well as formally unnamed Helicobacteraceae were detected in human samples.…”

Today there is evidence that Helicobacter pylori has a critical role in different extragastric diseases. The discovery of a number of other novel Helicobacter species has stimulated the research in different extragastric diseases, in which an infectious hypothesis is plausible. Enterohepatic Helicobacter species have been hypothesized to play a role in different disorders, including hepatocellular carcinoma, gallstones formation and cholangiocellular carcinoma, as well as enteric diseases and inflammatory bowel diseases. Concerning the extragastric manifestations of H. pylori infection, idiopathic thrombocytopenic purpura, and sideropenic anemia represent, based on the current data, the diseases in which the pathogenic link appears to be strongest. There is also an increasing evidence for a possible association of H. pylori with cardiovascular disease.

In recent years, the importance of the histological diagnosis of gastritis on the basis of routinely obtained antral and corpus biopsies has increased enormously, which is owed not least of all to the discovery of Helicobacter pylori. The introduction of the Sydney system made it possible, for the first time, to grade histological parameters, identify topographical distribution and, finally, make a statement about the etiopathogenesis of the gastritis. Of pathogenetic importance is, in the first instance, the differentiation between gastritis with and gastritis without H pylori infection. The group of H pylori-associated gastritis can be further subdivided into forms of gastritis whose morphological distribution patterns usually identify them as sequelae of H pylori infection, while the group of gastritis unassociated with H pylori, can be differentiated into autoimmune, chemically induced reactive gastritis, ex-H pylori gastritis, Helicobacter heilmannii gastritis, Crohn's gastritis and a number of special forms of gastritis.

“…PCR products can subsequently be cloned and sequenced or analyzed by restriction fragment length polymorphism to identify the species and strain. 75 Electron microscopy has been advocated to differentiate Helicobacter species on the basis of typical morphologic criteria.

“…94,95 Only recently, an identical ''H heilmannii'' organism identified by PCR and urease-B gene sequencing has been found in a patient and 1 of his cats. 75 The possible risk of transmission of large GHLO to human patients is rather small, considering the greater than 90% prevalence in dogs and cats and the rare (Ͻ0.5%) occurrence in humans. Notwithstanding, proper hygienic control is necessary to keep the risk to a minimum.…”

The discovery of the spiral bacterium Helicobacter pylori and its causative role in gastric disease in humans has brought a dramatic change to gastroenterology. Although spiral bacteria have been known for more than a century to infect the stomachs of dogs and cats, recent research has been conducted mainly in the wake of interest in H. pylori. H. pylori has not been found in dogs and only very rarely in cats and zoonotic risk is minimal. A variety of other Helicobacter spp. can infect the stomach of pets; however, their pathogenic role is far from clear, and they have a small but real zoonotic potential. The prevalence of gastric Helicobacter spp. in dogs and cats is high, irrespective of clinical signs, and as in human medicine, mode of transmission is unclear. The relationship of Helicobacter spp. to gastric inflammation in cats and dogs is unresolved, with inflammation, glandular degeneration, and lymphoid follicle hyperplasia accompanying infection in some but not all subjects. Circulating anti-Helicobacter immunoglobulin G antibodies have been detected in 80% of dogs with naturally acquired infection and most dogs and cats with experimental infection. The gastric secretory axis is similar in infected and uninfected cats and dogs and no relationship of infection to gastrointestinal ulcers has been found. Differences in the pathogenicity of Helicobacter spp. are apparent, because infection with H pylori is associated with a more severe gastritis than infection with other Helicobacter spp. in both cats and dogs. Rapid urease test, histopathology, and touch cytology are all highly accurate invasive diagnostic tests for gastric Helicobacter-like organisms in dogs and cats, whereas culture and polymerase chain reaction are the only means to identify them to the species level. Urea breath and blood tests or serology can be used to diagnose Helicobacter spp. noninvasively in dogs and cats. Most therapeutic studies in pets have not shown long-term eradication of Helicobacter spp. Whether this is due to reinfection or recrudescence has not been established.
