Characteristics of escape mutations from occult hepatitis B virus infected patients with hematological malignancies in South Egypt

Figure 1 Phylogenetic tree constructed from the nucleotide sequences of the full hepatitis B virus genome. The phylogenetic tree is constructed by the neighbor joining method and significant bootstrap values (> 75%) are indicated in the tree roots. HBV sequences isolated from the studied cohort are indicated in bold. Reference sequences retrieved from the GenBank/EMBL/DDBJ are indicted by their accession numbers. The country origin of the reference sequences is indicated in brackets. HBV genotypes A-H are indicated in the cluster roots. HBV: Hepatitis B virus.
