UPGMA dendrogram based on 276 nucleotides of ORF 2 in 640 HEV strains. The genotypes and subdivision of genotype 3 into two groups are shown on the branches. The details of the branch formed by 3-I strains are shown in the figure. The subtypes are indicated on the branches. Origin of strains from Swedish pigs is indicated on the branch, by the designation of the pig farm. Strains sequenced and described in this study are marked in bold. Strains from animals are indicated in italic. Boot strap values of 1000 replica are indicated below the branches.
