The presence of &lt;i&gt;H.\u00a0pylori&lt;\/i&gt; was monitored in the oral cavity of 22 patients with duodenal ulcer, before and after antibiotic treatment and of 24 hospital employees who were or were not professionally exposed to &lt;i&gt;H.\u00a0pylori.&lt;\/i&gt; Gastric infection was determined by breath test. Bacteria in the oral cavity were detected by nested PCR of samples containing saliva and dental plaque, using primers specific for &lt;i&gt;16S rRNA&lt;\/i&gt; and &lt;i&gt;ureC&lt;\/i&gt; genes. Before treatment, 9 out of 22 infected ulcer patients harbored &lt;i&gt;H.\u00a0pylori&lt;\/i&gt; in their oral cavity. Bacteria disappeared from the oral cavity of 3 of 7 cured patients. Twelve of 17 exposed subjects harbored &lt;i&gt;H. pylori&lt;\/i&gt; in their oral cavity, while no bacteria could be detected in the mouths of the 7 nonexposed subjects. Presence of bacteria in the oral cavity reflects handling of contaminants; it does not correlate with gastric infection and does not seem to promote it.<\/jats:p>","DOI":"10.1159\/000007659","type":"journal-article","created":{"date-parts":[[2003,4,15]],"date-time":"2003-04-15T15:42:49Z","timestamp":1050421369000},"page":"196-202","source":"Crossref","is-referenced-by-count":28,"title":["&lt;i&gt;Helicobacter pylori&lt;\/i&gt; in the Oral Cavity Reflects Handling of Contaminants but Not Gastric Infection"],"prefix":"10.1159","volume":"60","author":[{"given":"C.","family":"Dor\u00e9-Davin","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Heitz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H.","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Herranz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.L.","family":"Blum","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"I.","family":"Corth\u00e9sy-Theulaz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[1999,5,14]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1097\/00004836-199604000-00004"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1080\/00365529850166194"}],"container-title":["Digestion"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/7659","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/7659","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T04:40:34Z","timestamp":1745469634000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000007659"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1999]]},"references-count":2,"journal-issue":{"issue":"3","published-online":{"date-parts":[[1999,6,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000007659","archive":["Portico"],"relation":{},"ISSN":["0012-2823","1421-9867"],"issn-type":[{"value":"0012-2823","type":"print"},{"value":"1421-9867","type":"electronic"}],"subject":[],"published":{"date-parts":[[1999]]}}}
