Detection of Helicobacter pylori in dental plaque by reverse transcription-polymerase chain reaction

Abstract excerpt

To investigate whether the oral cavity is a potential reservoir and possible sanctuary for Helicobacter pylori, supragingival and subgingival plaques were analyzed by a Helicobacter genus-specific reverse transcriptase-polymerase chain reaction based on the sequence data of H. pylori 16S rRNA. The amplified 500-bp DNA fragment was identified by ethidium bromide staining after agarose gel electrophoresis and by...
