Phylogenetic analysis based on 86 sequences of 431 nucleotides within the HBsAg region. The evolutionary history was inferred using the Neighbor-Joining method. The evolutionary distances were computed using the Maximum Composite Likelihood method and are in the units of the number of base substitutions per site. There were a total of 431 positions in the final dataset. Phylogenetic analyses were conducted in MEGA4. Sequences from patients included in this study are labeled with a red dot. Reference sequences are indicated by their accession number.
