Abstract: Helicobacter pylori was described as a causative agent of gastric pathologies in human as gastritis, gastric MALT lymphoma and carcinoma. The genus of these tightly coiled bacteria has been intensively studied and described in different animals. The aim of this study was to evaluate the macroscopic and microscopic changes in feline gastric mucosa positive for Helicobacter pylori. Embedded paraffin gastric samples from 20 stray cats were selected from the archive of the veterinary anatomic pathology laboratory based on previous positive results for helicobacter spp in the Rapid Urease Test (RUT) and cytology. Infection by Helicobacter sp. was confirmed by histopathology using the Warthin Starry (WS) staining method. Archived data recorded during gastroscopy were analysed and related to microscopic findings obtained from histopathology. Gastroscopy evaluation showed changes as edema, hyperemia, erosion and/or ulcer in 30% of the animals. On histopathological analysis mild or moderate inflammatory cell infiltrate was observed in 75% of them.
