Figure 2.
A phylogenetic tree constructed by the neighbor-joining method based on the ORF2 sequence of the Korean HEV in question, 2010-JKSH-CYY (HM769726), and 42 HEV reference strains with genotypes 1 - 4 (G1-G4). All strains were separated into four groups according to their genotype. H: isolated from humans; P: isolated from pigs. Sequence analysis was conducted using the software VectorNTI and MEGA 5.04. Bootstrap values are indicated for the major nodes as a percentage of the data obtained from 1000 resamplings.
