Emergence of Hepatitis B Virus Genotype F in Aligarh Region of North India

Figure 1

Phylogenetic analysis of isolates 3R, 5R, 9R, 10R, 11R, 12R, 13R, 14R, 15R, and 17R (genotype D) from Aligarh region was compared with reference strains from Genbank; phylogenetic analysis was based on comparison of 305 bp of the S-gene and constructed using neighbour joining method (bootstrap test of phylogeny). Robustness of the phylogenetic analysis was evaluated by a 1000 bootstrap replications. Genetic distances were calculated using the Kimura 2-parameter model of nucleotide substitution, MEGA 4 package.
