Prevalence of EBV genotypes in Polish, Taiwanese and Arabic healthy students and association between genotypes and 30-bp deletion in the LMP-1 gene phylogenetic analysis

The aim of this study was to compare the prevalence of EBV genotype and del-LMP-1 in saliva from Polish, Taiwanese and Arabic healthy students. The study group consisted of 56 healthy students; 24 of them Polish, 25 Taiwanese, and 7 Arabic. Typing was carried out using PCR with EBNA-2 primers. A detection of LMP-1 variants was also performed using PCR. EBV DNA was detected in 22 investigated samples (39.3%). Type 1 of the virus was dominant in both Polish and Taiwanese group. Among 62.5% Taiwanese with EBV 1 and 55.6% Polish detected EBV with 30-bp deletion in LMP-1 gene.
