Molecular epidemiology and putative origin of hepatitis C virus in random volunteers from Argentina

Figure 2 Phylogenetic trees performed by the Neighbor-Joining method. NS5B sequences obtained from the volunteers whose respective hepatitis C virus (HCV) isolates had been classified as HCV-1a (n = 5), HCV-1b (n = 5) or HCV-2c (n = 5) were respectively analyzed in panels A, B and C together with 100 HCV-1a, 100 HCV-1b or 81 HCV-2c sequences downloaded from the GenBank. The respective consensus trees are shown after analyzing 100 replicate trees for each HCV subtype. A distance scale (in nucleotide substitutions per position) is shown in each panel. Arrows indicate sequences obtained from Argentinian volunteers.
