Samples from the stomach antrum, body and fundus were collected from 32 mixed-breed stray domestic cats using gastroscopy. Urease testing and cytological analysis were performed in fresh samples. Tissue sections were processed and stained with hematoxylin and eosin (H&E) and the Warthin?Starry (WS) silver staining methods for histopathological examination. Helicobacter spp. were detected in 100% of samples subjected to silver staining and cytological analysis, and in 96.9% of samples subjected to urease testing. In 87.5% of the cats, mononuclear inflammatory-cell infiltrates were identified. The graduation and distribution of inflammatory infiltrates in these cats revealed mild (78.1%) to moderate (9.4%) inflammatory changes in at least one gastric region. These changes were independent of the colonization score. Hyperplasia of the lymphoid follicles was detected in three cats. Cats of blood group A are often colonized by Helicobacter spp. and the macroscopic and microscopic findings are consistent with studies in domestic cats reported to date, concluding that the most common blood group in cats is not associated with high susceptibility to symptomatic gastritis.  aBlood group antigens  aCats  aEndoscopy  aGastritis  aHistopathology  aGastrite  aHistopatologia  aDomestic cats  aEndoscopia  aFelino  aGrupo sanguíneo A  aHelicobacter spp1 aCASCON, C.
