عنوان انگلیسی Comparative Molecular PCR-RFLP Study of Native Herpes Simplex Virus Type 1 (HSV-1) with KOS Strain
چکیده انگلیسی مقاله Background: Recent research on several DNA fragments covering open reading frames (ORF) 1-37 shows a new genetic marker in ORF 6 which is specific for differentiating wild-type varicella-zoster virus (VZV) strains from Oka varicella vaccine strain. On the other hand, herpes simplex virus (HSV) genome analysis by restriction enzymes is used to differentiate types one and two of the virus and even strains of each type. Previous studies using PCR-sequencing technique have shown that the thymidine kinase (TK) gene of HSV-1 is polymorphic. Methods: In this study, TK gene and DNA binding protein (UL29) gene of HSV-1 were selected. Both genes were analyzed with restriction endonucleases in order to identify a genetic marker for differentiating native strains of HSV-1 from the foreign strain. Three isolates of HSV-1 as well as standard strain of KOS were propagated in Vero cells. Initially, a pair of specific primers for each gene was designed to amplify UL29 and TK genes of these isolates. Subsequently, PCR products of these genes were digested separately with five restriction enzymes and subjected to polyacrylamide gel electrophoresis. Results: Using PCR-RFLP (Restriction fragment length polymorphisms) technique, results indicate that the patterns of restriction endonuclease digestion of UL29 and TK genes of the three isolates show no differences when compared to KOS strain. Conclusion: The genotypes of Iranian isolates are the same as KOS genotype and both genotypes are derived from a common ancestor. Hence, it can be postulated that in the process of random population flow among Iran, Europe and USA, the original KOS strain infected the Iranian population at some point in time. Iran. Biomed.
