Evidence for the occurrence of the same strain of Campylobacter pylori in the stomach and dental plaque

Abstract

Restriction endonuclease analysis with HindIII, HaeMI, and BglII endonucleases of DNA extracted from each of eight colonies of Campylobacter pylori subcultured from a stomach biopsy and from each of eight colonies subcultured from dental plaque of the same patient indicated that at least three strains were present in the dental plaque but only one strain was present in the biopsy. One of the dental strains had restriction patterns indistinguishable from those of the biopsy isolate, providing evidence that both sites were infected with the same strain of C. pylori.

Local immune response in Helicobacter pylori‐infected cats and identification of H. pylori in saliva, gastric fluid and faeces

“…The bars show the mean OD at 405 nm from a group of four cats, and the brackets enclose nasopharynx, colonic contents, urethra and vagina have failed. 48 H. pylori has been infrequently isolated from dental plaque 49,50 and saliva of humans. 51 Although H. pylori has been documented by PCR in human faeces and dental plaque [52][53][54][55] and H. mustelae has been isolated from ferret faeces, 56,57 only recently has H. pylori been cultured from human faeces.…”

Reservoirs of Helicobacter pylori and Modes of Transmission

“…Shames et al [63], using a restriction endonuclease analysis of DNA, reported that the same strain of H. pylori was present in stomach and dental plaque.…”

Helicobacter pylori in the oral cavity and gastric mucosa: a meta-analysis

“…Studies (10)(11)(12)(13)(14) have described evidence supporting the role of the oral cavity as a reservoir for H. pylori. Occurrence of the same strain of H. pylori in the stomach and DP has been reported (15). Several studies showed that systemic therapy failed to clear H. pylori from DP, despite its clearance from the stomach (7,16,17).…”
