    Abstract:
    From a blood serum of patients with chronic posttransfusional non-A, non-B hepatitis the genomic RNA of hepatitis C virus (HCV) was isolated. Using RT-PCR (reverse transcription-polymerase chain reaction) there were synthesized and cloned cDNA fragments, representing 3 regions of the genome of a new virus isolate (HCV-R): 5'-nontranslating region, a core gene and a part of the nonstructural region NS3/NS4. Analysis of the nucleotide and of the amino acid sequences of a core and NS3/NS4 regions revealed significant difference between isolates from Russia (HCV-R) and from Japan (HCV-J). Nucleotide sequence homology between them was 90.0-90.87%, while homology between Russian and American isolates (USA-PT) complised 95.27-97.32%. No essential variations were found in the nucleotide sequences of 5'-nontranslating region of all three HCV isolates.
