Maximum-likelihood phylogenetic tree obtained for the E1-E2 region. Maximum-likelihood phylogenetic tree obtained for the E1-E2 region of cloned sequences from patient C1 (black triangles), patient C2 (white circles), patient C3 (white squares) and 35 reference sequences. Numbers inside shapes indicate number of identical sequences sampled. All sequences belong to HCV subtype 1b. Only bootstrap support values higher than 70% are indicated. The scale bar represents genetic distance.
