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.
