Phylogenetic analysis of CyHV-3 genome sequences. The analysis was based on full-length genome sequences excluding one of the terminal direct repeats. The two previously described lineages are indicated. The phylogenetic tree was built using UPGMA in MEGA6 with 1000 replicates. Values on internal branches refer to the percentage of bootstrap replicates in which the branch was found; only values greater than 50% are shown. The scale shows the number of substitutions per nucleotide.
