Capripoxvirus disease in an Arabian oryx (Oryx leucoryx) from Saudi Arabia.

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, greater than 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.
