PURPOSE: To investigate the incidence of Helicobacter sp in dogs from the animal colony of UNESP. METHODS: One hundred and nine dogs from the animal colony of UNESP- Botucatu, SP were studied to verify the presence of Helicobacter sp. The methods used were: histopathology stained by Giemsa, rapid urease test (RUT) and the prevalence of Helicobacter pylori was tested by serologic immunocromatography. RESULTS: The presence of Helicobacter was found in 99% of the cases when using the histopathology and RUT methods. The prevalence of H. pylori tested by immunocromatography was of 78.8%. CONCLUSION: The forms found under microscopy oimmersion were contrary to the serologic test, where forms compatible to the H. heilmannii were found in the majority of the samples. A second form of Helicobacter with different morphologic characteristics from the human H. pylori was also found.
