In mammals, different Helicobacter species have been detected and associated with gastrointestinal pathologies. The presence of gastric Helicobacter-like organisms (HLO) in the stomach of dogs and cats has been known for many years but the relationship of those organisms to gastric disease remains controversial. The objective of this study was an approach to evaluate the prevalence of gastric lesions in dogs asymptomatic. Samples were collected from 40 dog's stomachs (regions pyloric) post-mortem with ages between 5 and 12 years, 27 females and 13 males and were examined by histopathology in the diagnostic service of pathological anatomy. None of these dogs had shown any preceding clinical symptoms of gastrointestinal disease. Additionally the special coloration was used Warthing-Starry. In the macroscopic study we found 5/40 acute gastritis, 13/40 chronic gastritis and 22/40 atrophic chronic gastritis. The predominant cellular infiltrated lymphocytic and plasmocytic (35/40). Hyperplastic of lymphoid follicular and intestinal metaplasia (32/40). All samples that were positive for Warthing-Starry stain. The presence of bacterium spiral short in the gastric mucous was observed in all the cases associated with gastric lesions. Future studies will be necessary to achieve the culture of this bacteria in order to identify its species and relation to pathology in dog. From these results seem to elicit further research to magnify the population and its association to the mechanism of pathogenesis of the bacterium in dog.
