Phylogenetic analysis of HBV complete genome of Cuban isolates.

<p>Genetic distance was estimated by Kimura 2 parameters and phylogenetic tree was constructed with the Neighbor joining method. Numbers at each node correspond to bootstrap values (greater than 50%) obtained with 500 replicates. Isolates are designated by their GenBank accession number, followed by their country of origin, except for Cuban ones which are shown in bold.
