Prevalência de helicobactérias e alterações na mucosa gástrica de cães saudáveis Prevalence of helicobacters and alterations in gastric mucosa of healthy dogs

<abstract language="eng">Prevalence, distribution and density of gastric helicobacter colonization were determined in 50 healthy dogs, characterizing the macroscopic and microcospic aspects of their mucosa. Helicobacter prevalence was 96%, with greater distribution in the gastric fundus and body. Although the presence of macroscopic alterations was high (58%), it was characterized as mild due to the predominance of less severe ones (65.5%). High prevalence of mostly monoclear cell infriltate (64.7%) was noted. Association between the presence of helicobacter and macro and microscopic alterations was not observed
