Phylogenetic tree for HCV/1 NS5B gene sequences constructed using the neighbor-joining method (MEGA 6 Software).

<p>Tree shows the phylogenetic relationship of 25 HCV-NS5B reference sequences and 36 HCV-NS5B sequences from this study. The reference HCV/1 subgenotype isolates are indicated by different colored branches along with their accession numbers and countries of origin. The 36 isolates from the present study are indicated by closed red triangles. Bootstrap values indicate the major nodes as a percentage of the data obtained from 1000 replications.
