| helicobacter pylori in the canadian arctic: seroprevalence and detection in community water samples. | many north american arctic communities are characterized by risk markers associated with helicobacter pylori (h. pylori) infection, including overcrowded housing and inadequate water supply and sanitation systems. our aim was to determine the seroprevalence of h. pylori infection in two traditional inuit communities in the central canadian arctic and to test for the presence of h. pylori, by polymerase chain reaction (pcr), in local water supplies. | 1999 | 10406242 |
