Phylogenetic tree of the gamma- and betaherpesviruses. The tree was constructed using the sequences detected in this study (bold) in addition to the species viruses inside the Betaherpesvirinae and Gammaherpesvirinae subfamilies retrieved from the International Committee on Taxonomy of Viruses, and the few available sequences of herpesvirus in rodent hosts obtained from GenBank. Cyprinid herpesvirus (no. MG925486) was used as an outgroup. A maximum likelihood tree was constructed based on a discrete gamma distribution and the rate of variation model allowed for some sites to be evolutionarily invariable. All positions containing gaps and missing data were eliminated. There were a total of 81 positions in the dataset. Bootstrap support above 75 is shown in black circles. Evolutionary analyses were conducted in MEGA6 (Tamura et al. 2013).
