Unrooted phylogeneitc tree based on the Npro sequences. Phylogenetic tree of the Npro from three BVDV positive samples was constructed by the neighbor-joining (NJ) method with the sequences published in GenBank. The nucleotide length of the Npro sequence used for the analysis was 504 bp. The numbers at the phylogenetic branches indicated the bootstrap values (1000 replicates) in percentage supporting each group. The bar represented a genetic distance
