Co-evolution of carnivore papillomaviruses from Omega-, Lambda-, Triesta-, Tau-, Dyonu-, Chi- and Dyothetapapillomaviruses. Clades of concatenated E1–E2–L1 maximum-likelihood phylogenetic tree (see Fig. 3). All Carnivora papillomaviruses known to date are present in the six clades and these are linked to their host phylogenies.
