The purpose of the present study was to examine whether bovine papillomavirus (BPV) DNA can be detected on the normal skin and in the habitual surroundings of horses with and without equine sarcoids by means of superficially taken swabs. In affected horses, no significant difference in presence of BPV-DNA could be observed between samples obtained from the equine sarcoid surface, from normal skin close to the tumour and from a normal skin site in direct contact with the tumour. From the group of healthy horses living in contact with affected horses, 44% were BPV-DNA positive. The surroundings of affected and non-affected horses are probably not a major source of BPV-DNA contamination. It can be concluded that BPV-DNA is present on the normal skin of horses affected by equine sarcoid and to a lesser degree, on the normal skin of horses living in contact with affected horses.
