Phylogenetic tree analysis of the S gene sequences of strains isolated in this study. The HBV strains from different genotypes (A to H) are obtained from GenBank. The GenBank HBV sequences are indicated with their accession number followed by genotypes. The sequences determined in this study are indicated by isolate number, starting with HBSAG or OBI, and are labelled with black circles and triangles for HBsAg-positive patients and patients with occult HBV infection, respectively.
