Figure 2.

The enlarged branch of HEV3 subtype 3f strains in a UPGMA phylogenetic tree based on 325 nucleotides of partial ORF1 for genotype 3. Bootstrap values from 1,000 replicas are given below the branches. The strains from pigs are given in red, those from wild boars in green and those from humans in blue. The farm designations where the strains were collected are given on the branches and the region of origin of the farms are given at the nodes. The farms in which samples were collected in 2007 and 2009 are indicated with year after the name of the farm. Farms marked with an asterisk indicate farms with strains collected more than a year apart. Accession number and origin of the strains are given at the nodes
