Reconstructed phylogenetic tree of <i>preC/C</i> region in the HBV genome.

<p>Phylogenetic analysis inferred from distance analysis (Kimura 2 parameters model) and neighbor-joining reconstruction from <i>preC/C</i> region of OBI sample sequences showing that the HBV sequences mostly clustered in the HBV genotype E branch. HBV sequences are referred to as “number”, i.e., “017”. The HBV sequences were compared to HBV reference sequences gathering the 8 HBV genotypes (NCBI-Genbank accession numbers are denoted). The numbers at the nodes indicate bootstrapping values in percentage of 1000 replicates.
