Fig. 1From: Hepatitis D virus and hepatitis B virus infection in Amerindian communities of the Amazonas state, ColombiaUnrooted phylogenetic tree of HBV ORF S generated by Neighbor Joining method. The sequences of this study (799, 1013, 851, 862, 817, 520, 680, 02 and893_AMZ) indicated with red circles, were compared with representative sequences of all HBV genotypes (A-I). The sequences are denoted with the GenBank accession number, genotype, country and year in which they were reported. The tree was generated using the software MEGA 5.1. Bootstrap values (indicated by arabic numbers) were obtained from 1000 replications. The black circle indicates the location of the positive controlBack to article page
