Helicobacter, Gram negative bacterias are curved or helicoidal microorganisms, widely spread in the stomach of humans and several animals, found as normal microbiota or causing of gastrointestinal pathologies. The objective of the work consisted of determining the relation between the presence and loads of helicobacterias in canine, with the degree of contact with its positive owners proprietors to these bacteria using rapid urease test. A sample of 31 healthy dogs of the city of Chillan, Chile were used, from which gastric fungus biopsies were obtained by endoscopy. These biopsies were put under the Rapid Urease Test. The owner of these canines were all positive for helicobacteria, determined by means of the same test. Ninety sevent percent of the canine biopsies were positive for helicobacteria Thirty nine percent of the biopsies with the fastest positive reaction to the urease test belonged to canines with a high contact grade to their owners. The results suggest that the high charges of helicobacteria found in canines could be because of the higher contact grade of these animals with their owner It would be important then to determine in future studies, whether if these pets could be a reserve or a transmission source for people, or viceverse, and the bacterial species involved.
