Figure 1.

Phylogenetic relationships amongst HEV-A isolates. The neighbour-joining tree was established from alignments of the full genome nucleotide (a) and amino acid sequences (b). The percentage of bootstrap replicates supporting the trees are indicated at the nodes. The branch lengths are proportional to the genetic distances corrected using Kimura-two-parameter substitution model.
