Phylogenetic tree based on a 186-bp nucleotide sequences of HEV-ORF2. The tree was constructed by the neighbour-joining method using 46 animal and human HEV reference strains. Strains characterised in this study were indicated with symbol filled triangle. The internal node numbers indicated the bootstrap values as a percentage obtained from 1000 replications. The Arabic numbers and the English letters outside of the dashed curves indicate the genotype and subtype. The bar on the tree shows the scale of 0.05 % nucleotide substitution per site. GenBank accession numbers, country and species of origin are indicated for each isolate represented on the tree
