Maximum Likelihood (ML) phylogenetic tree of the Core gene sequences from 47 reference sequences and 50 sample sequences. The tree branches, including the outer circle, are colored according to the HCV types and subtypes 1a and 1b. The tree scale refers to the number of nucleotide substitutions per site. The ML tree of the Core region showed a very good grouping of the different genotypes, for reference and sample sequences
