| Abstract: | Feline sarcoids are uncommon dermal neoplasms that are thought to be caused by papillomaviral (PV) infection. Feline sarcoid‐associated PV (FeSarPV) has been consistently detected in sarcoids from North American and New Zealand cats but has not been detected within any other feline sample. This suggests that feline sarcoids may develop due to cross‐species infection by a PV from an unidentified reservoir host. While there is some epidemiological evidence to suggest that cattle are the reservoir host of FeSarPV, this PV has never been identified within any bovine sample. In this study both consensus PCR primers and primers specific to FeSarPV were used to investigate the presence of PV DNA within five fibropapillomas and 18 samples of inflammatory skin disease from cattle. Consensus primers amplified bovine PV‐2 DNA from four fibropapillomas, but none of the dermatitis samples. However, specific primers amplified FeSarPV DNA from four fibropapillomas and five inflammatory skin lesions. To the best of our knowledge this is the first time that FeSarPV has been detected within any sample other than a feline sarcoid. The ability of FeSarPV to asymptomatically infect bovine skin suggests that cattle are the reservoir host of this PV and feline sarcoids could be the result of cross‐species infection of a dead‐end host by a bovine PV. |
