Nucleotide neighbor-joining distance tree (maximum composite likelihood substitution model) for the partial DNA polymerase gene (UL30) showing the avian herpesvirus species belonging to Iltovirus genus and representatives from Mardivirus genus. Strains detected in the present study are followed by black dots. The numbers at each node are bootstrap values greater than 70% from 500 replicates. The tree is drawn to scale, with branch lengths in the same units as those of the evolutionary distances used to infer the phylogenetic tree.
