title: An outbreak of encephalitis in pigeons (Columba livia) in the Canary Islands (Spain).
abstract: An encephalitic disease in pigeons, characterized by paralysis of extremities, torticollis, head tremor, and diarrhea, is described. The negative titers in the hemagglutination tests, the presence of Feulgen-positive intranuclear inclusions in the cells of the granular layer of the cerebellum and the fibroblast culture, and the presence of viral particles with an icosahedral-herpetic morphology and a diameter of 100-170 nm all indicate that the etiology of this outbreak may be related to the encephalitis caused by herpesvirus, at present diagnosed only in Iraq and some African countries.
