From: Genetic heterogeneity of swine hepatitis E virus isolates from Yunnan province, China in 2011–2012
Phylogenetic tree constructed by aligning the swine HEV strains detected in 2011. Analyses based on nine isolated strains and 38 full length genomic references sequences. The tree was constructed by the Neighbor joining method using MEGA 5.05. Reference sequences are labeled with the GenBank accession number, the Country and host of the strain was isolated.
