Figure 2From: Isolation and characterization of two new hepatitis E virus genotype 1 strains from two mini-outbreaks in Lahore, PakistanPhylogenetic analysis based on the complete ORF2 sequence of the isolate in this study and other HEV genotypes 1-4, using the neighbor-joining method and evaluated using the interior branch test method with Mega 4 software. Percent bootstrap support is indicated at each node. The scale bar represents nucleotide substitutions per base. GenBank accession numbers of sequences used for phylogenetic analysis were: HEV type 1 (M80581), type 2 (M74506), type 3 (AB089824) and type 4 (AB097812).Back to article page
