Avian Pox in Sanderlings from Florida

Asian pox was diagnosed in three sanderlings (Calidris alba) on Sanibel Island, Florida (USA) in February 1997. All three cases had large tumor-like lesions which contributed significantly to their mortality. Poxvirus infection was confirmed by cytology, histopathology, and electron microscopy. This is the first report of poxvirus infection in sanderlings.
