Plain-English summary
A group of twenty dogs in Venezuela was examined for stomach issues, and many showed signs of gastritis, which is inflammation of the stomach lining. Nineteen of these dogs had mild to severe gastritis, while only one had a healthy stomach. Researchers found DNA from a type of bacteria called non-H. pylori helicobacters in eighteen of the dogs with gastritis and in the one healthy dog. However, they did not find a clear link between the presence of these bacteria and the severity of the gastritis. More research is needed to understand the role of these bacteria in stomach problems in dogs.

Abstract
Non-H. pylori helicobacters (NHPH) have been demonstrated as gastric spiral-shaped bacteria in specimens obtained from dogs; however, their roles in the pathogenesis of upper gastrointestinal disease have not yet been clearly established. The purpose of this study was to evaluate the prevalence of NHPH DNA in the gastric mucosa of dogs and its association with histopathology. Helicobacter was detected through histopathological techniques, PCR, and FISH analysis from fundic biopsies of twenty dogs with or without signs of gastrointestinal disease. PCR and FISH were based on partial 16S rRNA gene sequences. Nineteen dogs showed mild to marked gastritis in the fundus, and only one dog had a healthy gastric mucosa. NHPH DNA was detected in 18 dogs with gastritis and one with normal gastric mucosa. However, there was no significant correlation between the presence of NHPH DNA and the degree of gastritis. These results show a high prevalence of NHPH DNA in the gastric mucosa of dogs from Venezuela. Further studies are necessary to determine a possible association between a specific NHPH species and the degree of gastritis.
