From: Isolation and phylogenetic analysis of orf virus from the sheep herd outbreak in northeast China
Phylogenetic analysis based on nucleotide sequences of ORFV011. The phylogenetic relationship was constructed by the neighbor-joining algorithm using MEGA 5.0 software; one thousand bootstrap replicates were subjected to nucleotide sequence distance (cut-off value of 50% from 1000 bootstrap replicates). All bootstrap values are displayed above branches. ·: NA1/11 isolated in this study; black triangle: eight different Chinese strains from database.
