[Incorporation of a DNA replica of the genome of the tick-borne encephalitis virus into cellular DNA]. / Vstraivanie DNK-kopii genoma virusa kleshchevogo éntsefalita v kletochnuiu DNK.

DNA from mouse cells chronically infected with tick-borne encephalitis (TBE) virus was treated with restrictases, the resulting fragments were fractionated by size by gel electrophoresis, denaturated, and transferred from gel on nitro-cellulose filters. The fragments containing virus-specific sequences were detected by hybridization with 32P-DNA replicas of TBE genome RNA synthesized using reverse transcriptase. The presence of virus-specific sequences in DNA fragments from chronically infected cells proves the possibility of integration of DNA-replicas of TBE virus genome and genome of chronically infected cells.
