Phylogenetic analysis of the 5′-UTR region of 81 HCV samples from Danish patients compared with the sequences obtained from the two HCV genotyping panels from Essen and NIH, and 11 reference sequences from Fig. 2 (shown in bold). The genotype established by E1 analysis is indicated for 71 of the 81 clinical isolates. The phylogenetic tree was constructed by using the Kimura-2-parameter with the neighbor-joining method. The numbers on the branching represent bootstrap 1000 values.
