Abstract
Poxvirus was identified morphologically from skin lesions in captive and free-ranging bottlenosed dolphins, Tursiops truncatus and a stranded Atlantic white-sided dolphin, Lagenorhynchus acutus. The lesions, commonly referred to as ring or pinhole lesions, appear as solitary or coalesced circular grey blemishes. Advanced ring lesions may take the form of black punctiform stippled patterns known as tattoo. Histologically, the stratum externum is thickened and there is ballooning degeneration and eosinophilic intracytoplasmic inclusions in the stratum intermedium. These inclusions contain virus particles which exhibit typical poxvirus morphology. Stress, environmental conditions and general health may play a major role in the clinical manifestation of dolphin pox.
