Figure 1From: Detection of lamivudine-resistant variants and mutations related to reduced antigenicity of HBsAg in individuals from the cities of Santos and São Paulo, BrazilPhylogenetic relationship generated from 34 HBV sequences. A bootstrap analysis with 1,000 replications was performed to confirm the reliability of the tree. The approximate likelihood ratio test (aLRT) values ≥ 70% are indicated at the nodes. Nucleotide sequences were compared with reference sequences, which are indicated by accession number and alphabetical letter. Samples from the Blood Center of Santos are indicated with squares, and those from São Paulo are indicated with triangles.Back to article page
