seroprevalence of helicobacter pylori, incidence of gastric cancer, and peptic ulcer-associated hospitalizations in a canadian indian population.the living conditions of many aboriginal communities in canada may place their residents at risk for h. pylori infection. our aims were to determine: (1) the seroprevalence of h. pylori in a traditional indian community, (2) the clinical relevance of h. pylori infection in this population, and (3) if h. pylori could be identified by polymerase chain reaction from the local water. a demographic questionnaire was administered, and blood was collected from subjects in an indian community in northwe ...199910219820
