Fig. 3From: Genetic polymorphisms of HLA-DP and isolated anti-HBc are important subsets of occult hepatitis B infection in Indonesian blood donors: a case-control studyNeighbour-joining phylogenetic tree for HBV strains in OBI subjects (indicated with solid circles). The phylogenetic analysis was performed based on 101Â bp of the partial X region. The bootstrap support for the consensus tree, inferred from 1000 replicates, is indicated for each branch. The evolutionary distances were computed using the maximum composite likelihood methodBack to article page
