In this study, we examined <jats:italic>H. pylori<\/jats:italic> DNA in peripheral blood and gastric mucosa of patients with peptic ulcer or chronic gastritis by polymerase chain reaction (PCR). We found <jats:italic>H. pylori<\/jats:italic> DNA in 15 of 20 gastric samples, and 9 of these specimens were positive for <jats:italic>H. pylori<\/jats:italic> culture. <jats:italic>H. pylori<\/jats:italic> DNA amplified by PCR was positive in the peripheral blood of three patients, who all had duodenal ulcers. Gastric biopsy specimens from these three patients were all positive for <jats:italic>H. pylori<\/jats:italic> genes and <jats:italic>H. pylori<\/jats:italic> was isolated from these specimens. After the 16S rRNA gene sequences of three specimens from the same patient were obtained, we found that they were identical, which suggested that they are the same strain. Our findings suggest that <jats:italic>H. pylori<\/jats:italic> exists not only in gastric mucosa but also in peripheral blood, and it is possible that <jats:italic>H. pylori<\/jats:italic> can result in bacteremia.<\/jats:p>","DOI":"10.1111\/j.1600-0463.2006.apm_425.x","type":"journal-article","created":{"date-parts":[[2006,12,15]],"date-time":"2006-12-15T00:57:32Z","timestamp":1166144252000},"page":"851-856","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Detection
