Helicobacter are bacteria that colonize the gastric lumen and duodenum. In humans, these bacteria have been linked to gastritis, gastric ulcers, and gastric adenocarcinomas. The prevalence of Helicobacter in cats is high, but it is not known if there is an associated risk of gastric lesions. In this study, gastric samples were collected from 23 cats; 18 with no clinical signs, and 5 that had chronic vomiting. Samples were assessed microscopically for epithelial changes, as well as by PCR for the organism. The bacteria were detected in 20 of the 23 cats, four of which were from the cats experiencing chronic vomiting. No correlation was found between gastric inflammation and level of Helicobacter colonization. Helicobacter colonization was associated with increased epithelial proliferation in the stomach; thus, the authors postulate, it could contribute to gastric cancers. [MK] >> PubMed Abstract
