Figure 1From: Phylogenetic analysis of porcine parvoviruses from swine samples in ChinaPhylogenetic trees based on the neighbor-joining method for the 23 NS1 and 24 VP2 sequences. The tree was constructed using MEGA version 4.1. Bootstrap values obtained from 1000 replicates are shown at the major nodes. The NS1 and VP2 sequences of CPV and FPV were included as outgroups. The different groups in the trees are marked by different colors.Back to article page
