FIG. 4.

Phylogenetic relationships among parvoviruses from rodents, carnivores, and pigs. The four phylogenetic subgroups are shown. (A) All full-length sequences available for each virus species are included (labeled by their virus names and the GenBank accession numbers). Bootstrap values above 70 are shown (100 replications). (A) relationships based on nucleotide p distances among full-length genome sequences; (B to D) relationships based on the nucleotide Kimura two-parameter distances, Ds, and Da, respectively, for orf1; (E to G) relationships based on nucleotide Kimura two-parameter distances, Ds, and Da, respectively, for orf2. In orf1 (B to D), MousePV, HamsterPV, and MVM form a homogeneous cluster (B, grey box), to which LuIII (arrow) is an outlier. In contrast, in orf2 (E to G), MousePV and HamsterPV (E, open box) cluster with LuIII (arrow) and not with MVM (grey box). Virus abbreviations are in Table 1.
