Abstract

Attempts to produce equine sarcoid in donkeys were successful. Bovine papilloma was transferred between affected bulls and nonaffected donkeys by transplanting whole bovine papilloma tissue or by inoculating the skin with extract of bovine papilloma. Tumours were produced in 4 of 5 donkeys 9 to 16 days after infection. The clinical course of the developing tumours were studied. Surgical removal, macromorpho logical as well as histopathological studies were done. All clinical, macromorphological and histopathological features of the developing tumours were equivelant to those of equine sarcoid.
etiologic
It was concluded that bovine papilloma virus might be an agent of equine sarcoid in donkeys.
