Abstract
Oral squamous cell carcinomas (OSCCs) are common feline cancers. Why OSCCs are so common in cats is unknown; however, 25% of human OSCCs are caused by papillomaviruses (PVs). Two feline oral PVs (FcaPV-1 and 4) are recognized. As PVs are highly host and location specific, if PVs do cause feline OSCCs, FcaPV-1 and 4 are the most likely etiological agents. PCR primers specific for FcaPV-1 amplified DNA from 1 of 36 feline OSCCs and 1 of 16 inflammatory oral lesions. No DNA was amplified by primers specific for FcaPV-4. PV DNA was not amplified from any additional sample using consensus primers. No PV cytopathology was visible in the OSCC that contained FcaPV-1 DNA, but viral cytopathology was present in a focus of epithelial hyperplasia in the non-neoplastic sample. This study does not support a PV etiology of feline OSCCs, but shows that FcaPV-1 can asymptomatically infect the mouth of cats.
