Abstract
The equine sarcoid, one of the most common dermatological lesions in equids, is a benign, locally invasive dermal fibroblastic lesion. Previous studies have suggested an association with two bovine papilloma virus (BPV) types, BPV-1 and BPV-2. In the present study, we examined sarcoids from horses from two geographical areas, Switzerland and the UK, for the major transforming gene of BPV, E5. We detected BPV DNA for the E5 open reading frame and viral E5 RNA transcripts in most sarcoids. Sequence analysis of the E5 open reading frame of sarcoid-associated BPV detected several unique DNA sequence variants, three of which resulted in sarcoid specific amino acid sequence variations. It is unclear if these sequence variants contribute to the unique clinical presentation of the sarcoid. However, our work provides further evidence of the association between BPV and sarcoid development and the direct involvement of the virus in the pathogenesis of sarcoids.
