Figure. Neighbor-joining unrooted trees based on the full-length genome (A), E2 (B), 5′ untranslated region (C), and Npro (D) sequences of members of the genus Pestivirus. For phylogenetic tree construction, pestivirus sequences listed in the Table were used. Asterisks indicate strong statistical support for a node by a bootstrap value of 75%–100%. Scale bars represent estimated numbers of nucleotide substitutions per site. CSFV, classical swine fever virus; BVDV-1, bovine viral diarrhea virus type 1; BVDV-2, bovine viral diarrhea virus type 2; BDV, border disease virus.
