(a) Phylogram of morbillivirus phosphoprotein gene sequences. MEGA 5.0 was used to construct the maximum likelihood phylogenetic trees. A Tamura-Nei substitution model and a bootstrap resampling (1,000 replicates) were used to assess the reliability of the trees. Bootstrapping values are indicated as percentages next to the bifurcations. The new isolates from this study are shown in bold type. The scale bar shows the number of nucleotide substitutions per site. The name of the each sequence includes the virus name (DMV, dolphin morbillivirus; CeMV, cetacean morbillivirus; PMV, porpoise morbillivirus; PWMV, pilot whale morbillivirus; PPRV, peste-des-petits-ruminants virus; RPV; rinderpest virus; CDV, canine distemper virus; PDV, phocine distemper virus; MeV, measles virus), GenBank accession number, cetacean species (Gma, Globicephala macrorhynchus; Gme, Globicephala melas; Kb, Kogia breviceps; La, Lagenorhynchus albirostris; Pp, Phocoena phocoena; Sc, S. coeruleoalba; Tt, Tursiops truncatus), and the year and the geographic area of the stranding (At, Atlantic Ocean; ENoAt, Northeast Atlantic Ocean; Me, Mediterranean Sea; No, North Sea; Pa, Pacific Ocean). (b) DMV subtree branch length. Each branch length reflects the number of nucleotide substitutions per site.
