Geno- and seroprevalence of Felis domesticus Papillomavirus type 2 (FdPV2) in dermatologically healthy cats.

Background: Papillomaviruses can cause proliferative skin lesions ranging from benign hyperplasia to squamous cell carcinoma (SCC). However, asymptomatic infection is also possible. Several groups have detected Felis domesticus Papillomavirus type 2 (FdPV2) DNA in association with feline Bowenoid in situ carcinoma (BISC).

Antibody titres against canine papillomavirus 1 peak around clinical regression in naturally occurring oral papillomatosis.

Background: Most forms of canine papillomatosis are believed to be associated with papillomavirus infections. Canine papillomavirus type 1 (CPV1) is considered to be responsible for most oral cases and several forms of cutaneous papillomatosis.

Hypothesis/objectives: The aim of this study was to evaluate cases of naturally occurring oral papillomatosis with regard to the type of virus involved, antibody induction and remission time.

Serum antibodies and DNA indicate a high prevalence of equine papillomavirus 2 (EcPV2) among horses in Switzerland.

Background: The DNA of equine papillomavirus type 2 (EcPV2) is consistently found in equine papillomas and squamous cell carcinomas, indicating a causal association of EcPV2 in the pathogenesis of these tumours; however, little is known about the prevalence of this virus.

Hypothesis/objectives: The aim of this study was to determine the geno- and seroprevalence of EcPV2 in clinically healthy horses in Switzerland.

Animals: Fifty horses presented to the equine department of the university clinic, displaying no skin or mucous membrane lesions or severe signs of other diseases, were sampled.
