Lumpy skin disease caused by a capripoxvirus was observed in a captive-bred female Arabian oryx (Oryx leucoryx) at the National Wildlife Research Center, Taif, Saudi Arabia. Clinical signs included severe general depression with fever, anorexia, > 1,000 nodular cutaneous lesions and gradual recovery over 2 mo. The virus was found by electron microscopy and paired sera showed an increasing virus neutralization antibody titer against capripoxvirus. A serologic survey of the herd of 90 oryx showed a low prevalence (2%) of this infection. This report describes the first case of lumpy skin disease in an Arabian oryx.
