The aim of our study was to determine the prevalence and the intensity of infection with Helicobacter sp. in a group of 23 apparently healthy dogs in order to describe the morphological features of helicobacters, to detect histopathological changes in the gastric mucose, and to evaluate if there is a correlation between infection and eventual alterations in the stomach. Helicobacters were detected in the stomach of all dogs: they were spirally shaped with five to twelve turns. Helicobacters were presented in all examined parts of the stomach, i.e. in the fundus, corpus and antrum at equal density. They colonised the gastric mucus, gastric pits, and gastric glands. A mild and a moderate infection in 13% of the dogs and a severe infection in 74% of the digs was determined. Only a mild chronic gastritis was diagnosed in the gastric fundus in 16 dogs, of gastric corpus in 18 dogs, and in the antral region in 18 dogs. We concluded that gastritis is not directly linked to the helicobacter infection in our dogs.
