To assess the quality and public health risk of different types of water, the fecal indicator bacteria (FIB) are used. However, some pathogens, such as\n                      <jats:italic>Helicobacter pylori<\/jats:italic>\n                      , may be present in water when FIB cannot be found\n                      <jats:italic>.<\/jats:italic>\n                      <jats:italic>H\u00a0pylori<\/jats:italic>\n                      is recognized as the causative agent of chronic gastritis, peptic and duodenal ulcers, and gastric cancer.
