title: Presence of Helicobacter pylori in drinking water is associated with clinical infection.
abstract: Helicobacter pylori was detected using molecular methods in untreated well water. The presence of H. pylori in the wells correlated with infection in consumers and with the presence of Escherichia coli, indicating fecal contamination. Consumption of untreated well water should be considered a risk factor for H. pylori infection.
