Evidence for a distinct lineage among HBV/E isolates.

<p>Phylogenetic trees incorporate 231 HBV/E isolates whose complete nucleotide sequences were available in GenBank, including the 16 complete sequences of Angolan samples described in this study. The list of the isolates (GenBank accession numbers) is available in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0092223#pone.0092223.s001" target="_blank">Table S1</a>. Phylogenetic analyses were performed by (A) the maximum likelihood method and (B) by Bayesian Inference using the Bayesian Markov chain Monte Carlo (MCMC) statistical framework. Southwest African lineage shown in red ink was established with a posterior probability = 1.
