PERRONE, M et al. Identificación de genotipos  de Helicobacter pylori,  provenientes de muestras de placa dental  en  la población venezolana. Acta odontol. venez [online]. 2006, vol.44, n.1, pp.58-63. ISSN 0001-6365.

The aim of this study was to characterize the vacA and cagA genotypes of H. pylori strains from dental plaque of a Venezuelan population. 69 patients attending for routine gastroscopy were evaluated. Dental plaque samples were obtained for DNA extraction and PCR analysis. Amplification of glmM, vacA and cagA segments were performed as previously described. The results demonstrated that only 1/69 (1,4%) was positive for glmM amplification. None of the samples was typeable for vacA signal sequence genotype, vacA mid region or cagA. The results demonstrated that the prevalence of H. pylori in dental plaque of a Venezuelan population was not significant in this study and was not possible to identify the genotypes of H. pylori from dental plaque.
