Molecular-genetic analysis of DNA pol and TK of HSV-1 population using NGS technology]

It was determined the ratio of viral DNA and DNA from Vero cells using the polymerase chain reaction in real time in Vero cell lysate, infected with L2 strain of the herpes simplex virus type 1. Copy number of the virus reached a maximum after 24 hours of incubation of infection. Total DNA was isolated and sequenced using NGS technology by Ion Torrent device. Nucleotide sequences of the thymidine kinase gene (UL23) and DNA polymerase (UL30) were determined for a population of HSV-1 strain L2. Comparison of the primary structure of these genes with the corresponding nucleotide sequences of known strains of HSV-1 KOS and 17 was conducted. Differences in the structure of genes UL23 and UL30 between strain L2 and reference strains KOS and 17 are not important, because changes are found in non-conservative regions.
