The entire nucleotide sequences of three hepatitis C virus isolates in genetic groups 7-9 and comparison with those in the other eight genetic groups.

Abstract excerpt

We have proposed that hepatitis C virus should be classified into eleven genetic groups (types) which further divide into more than 80 genotypes (subtypes). However, only eight genetic groups (1-6, 10 and 11) have been defined on the basis of the full-length sequence. Hence, the entire nucleotide sequences of three HCV isolates in genetic groups 7-9 have now been determined. Phylogenetic analysis over the...
