FIG.1.

Phylogenetic analysis of the NS5b sequences of the samples containing HCV strains included in the panel (excluding those artificially coinfected) compared with NS5b reference sequences from GenBank and in-house NS5b sequences. HCV genotypes are designated by the numbers 1 to 5. Genomes from this study are indicated with black squares and with the sample number. The phylogenetic tree was constructed by using the neighbor-joining method in the PHYLIP package (15). Bootstrap values are shown at each main branch.
