In a 4-week-old female Chilean flamingo an extensive multinodular exophytic ulcerated cutaneous proliferation at the tibiotarsal joint was surgically removed. Histologically, there was a severe, acute, diffuse erosive and ulcerative, heterophilic dermatitis with severe, epidermal hyperplasia and eosinophilic, cytoplasmic inclusion bodies within hydropic degenerated keratinocytes. Electron microscopy revealed multiple biconcave brick-shaped virus particles measuring approximately 250 x 320 nm. Molecular analysis resulted in the identification of a Shearwater poxvirus strain SWPV-2 that is closely related to canary poxvirus. This strain was isolated recently from a wedge-tailed shearwater. Wedge-tailed shearwater are seabirds resident in the tropical parts of the Indian and Pacific oceans. The cutaneous form of avipoxvirus infection in birds manifests usually as a papillomatous proliferation at the non-feathered skin resembling macroscopically neoplasia or excessive granulation tissue. This case report represents the first description of a Shearwater poxvirus infection in a Chilean flamingo.  a0005-9366
