Résumé:
In dogs have found the presence of several species of the genus Helicobacter
transmission path as having the most accepted is by the oral-oral and/or anal-oral routes.
The discovery of Helicobacter spp. in feces and saliva of dogs in a related culture exam
of H. felis from the stomach of humans, reflects this zoonotic potential of species that
colonize the canine and feline stomach, whereas the infection of H. pylori in humans
are not correlated with pets. Aimed to verify the presence of bacteria of the Helicobacter
genus in the gastric mucosa of dogs of Environmental Management and Zoonosi and
identify the risk factors associated with the presence of bacteria. Of the 100 samples of
canine gastric mucosa 88% (88/100) were positive for Helicobacter spp. in the urease
test. There was no association (p> 0.05) of any of the three variables (age, sex and race)
analyzed with the results of the urease test, Gram and microbiological culture. The
histopathological results were mild to moderate inflammation in 47.6% (20/42)
stomachs, and were not found severe inflammation. Dogs with mild inflammation were
five (11.9%) were positive for Helicobacter spp. and one (2.4%) negative. With
moderate inflammation Three (7,1%) were negatives for Helicobacter spp., and eleven
(26.2%) were positive, these three (7,1%) dogs presented hyperplasia of lymphoid
follicles. Dogs with normal histology of the stomach were 52.4% (22/42), 14 (33.3%)
were positive for Helicobacter spp. and 8 (19.1%) were negative. The bacterium
Helicobacter spp. has a high prevalence in the dogs of zoonosi and cause gastritis
characterized by a lymphocytic infiltrate in the lamina propria and lymphoid follicular
hyperplasia, being necessary a thorough assessment of the risk factors for infection in
these animals, as well as further research on the age which bacteria transmission occurs.
Should be investigated the role of the dogs as reservoir of this microorganism and the
potential risk of transmission to humans.
