Phylogenetic tree of French canine PRV isolates based on partial nucleotide sequencing of the gC-encoding gene (UL44, 659 to 680 nt). The bootstrap percentage values are indicated at the nodes. The sequences of French PRV strains previously published [10], and sequences of two Asian PRV strains (Ea and Fa, GenBank accession numbers AF158090.1 and AF403051.1, respectively) were used to define the different genotypes and clades. These strains are indicated by a black dot.
