[Possibility for the presence of Helicobacter pylori in drinking well water].
Forty three well waters which are currently used as drinking water were studied for the presence of Helicobacter pylori. Using magnetic-beads purification and PCR amplification of H. pylori-specific gene, 4 of the 43 samples were positive for H. pylori-ureA gene (9.3%) and 1 of the 43 samples was positive for H. pylori-16SrRNA gene (2.3%). The presence of H. pylori-specific amplified product did not correlate with the type, depth and location of the wells. This study demonstrated that H. pylori can be transmitted via drinking water, especially well water in Japan.
