Phylogenetic relationships between ALPV and other chordopoxviruses. A maximum likelihood (ML) tree was constructed from multiple alignments of the concatenated amino acid sequences of the selected nine poxvirus core proteins using CLC Genomic Workbench (version 9.5.4, CLC bio, a QIAGEN Company, Prismet, Aarhus C, Denmark). The numbers on the left show bootstrap values as percentages. The ML tree is displayed as a phylogram. The labels at branch tips refer to original ChPV GenBank accession numbers followed by abbreviated species names. Saltwater crocodilepox virus (SwCRV1) [36] was used as an outgroup. The position of the novel ALPV is highlighted using a purple box and the subclade relevant to ALPV is shown with pink shading.
