Helicobacter pylori in the oral cavity: high prevalence and great DNA diversity.

Digestive diseases and sciences - 1 Nov 2000

Song Q, Spahr A, Schmid R M, Adler G, Bode G

Abstract excerpt

To test the hypothesis that Helicobacter pylori may be transmitted by the oral-oral route, we applied nested PCR and DNA sequencing to detect and analyze H. pylori DNA in the oral cavity of 20 adult patients undergoing endoscopy. Dental plaques of molars, premolars, and incisors and saliva were c...
