An exploratory study on the presence of Helicobacter heilmannii and Helicobacter billis in the feces of companion dogs.

This study revealed the negligible faecal transmission of H. pylori. Moreover, due to the detection of H. Heilmannii and H. billis in feces and their association with human gastric diseases, dog owners should be educated about the risks and transmission modes of zoonotic bacterial infections of dogs.
