The same papillomavirus is present in feline sarcoids from North America and New Zealand but not in any non-sarcoid feline samples.
Feline sarcoids are uncommon dermal neoplasms that are associated with papillomavirus (PV) infection. A single PV type, designated feline sarcoid-associated PV (FeSarPV), was detected in 9 feline sarcoids from North America. As FeSarPV has only been detected within feline sarcoids, the epidemiology of the infection remains unknown. The present study used polymerase chain reaction (PCR) to investigate whether this PV is also present within sarcoids from New Zealand cats. Additionally, as PVs are often host-specific, it was hypothesized that FeSarPV may often asymptomatically infect cats but rarely cause disease. To test this hypothesis, specific PCR primers were designed to investigate the presence of FeSarPV DNA within 120 samples from the skin and mouth of cats without sarcoids. Feline sarcoids from both New Zealand and North America contained FeSarPV DNA sequences. However, FeSarPV DNA was not detected within any non-sarcoid feline sample. To the authors' knowledge, this is the first time that FeSarPV has been reported in a country outside North America. As FeSarPV does not asymptomatically infect cats, feline sarcoids are likely due to cross-species infection. Although the reservoir host of FeSarPV is unknown, the host is present and has contact with cats, in both New Zealand and North America.
