The nested PCR assay yielded 56.9% (37/65) and 52.3% (11/21) positivity for the ordinary gastric carcinoma and control cases, respectively; these results were significantly than those of the one-stage PCR assay(13.5% and 0%, respectively). The EBV positivity showed similar rate in male and female patients (60% versus 52%, P > 0.05). The dominant genotype of EBV was 1 (92%) followed by mixture of 1+2 (5.4%) and 2 (2.6%). In conclusion, similar positivity rates of EBV in neoplastic and non-neoplastic tissues suggest that the relationship of this virus to the ordinary gastric carcinoma is not clear.eninfo:eu-repo/semantics/closedAccessEpstein-Barr viruspolymerase chain reactiongastric adenocarcinomavirus genotypeArticle426359363103587402-s2.0-0032414441N/AWOS:000079531900001Q4
