Phylogenetic tree based on the complete genomic sequences of genotype A hepatitis B virus (HBV) strains. A phylogenetic tree was constructed according to the neighbor-joining method based on the entire genomic sequences of the HBV strain (HB16-1360) obtained from the present case and representative genotype A HBV strains of subgenotypes A1 to A4. The HB16-1360 strain is highlighted in bold type with a closed box for visual clarity and the reported HBV strains are indicated with accession number and the name of the country where the strain was isolated. Asterisks indicate the HBV strains recovered from patients co-infected with human immunodeficiency virus or those who contracted acute HBV infection via sexual contact. Bootstrap values of > 70% are indicated for the nodes as a percentage obtained from 1000 resampling analyses of the data. The scale bar is in units of nucleotide substitutions per site.
