A papilloma virus (wart) is probably what causes horse sarcoids. A high proportion of sarcoids contain genetic material that is identical, or very closely related, to the bovine papilloma virus (BPV).sually the clinical appearance is adequate to make a diagnosis. Especially if several sarcoids of more than one type are present on the same horse. It is more difficult if only one occult sarcoid is present.
