Phylogenetic tree constructed based on partial NS1 amino acid sequences of reference PBoV and PBoV from Chinese slaughter pigs. Slaughter pig sequences are labeled with ▲ and their corresponding accession numbers. The phylogenetic tree was constructed by MEGA ver. 5.1 with neighbor-joining method using 1,000 bootstrap replicates.
