Rabbit oral papillomavirus (ROPV) is a mucosatropic papillomavirus
which naturally infects oral mucosal sites of domestic rabbits. In this
study, we tested the hypothesis that rabbit genital mucosa is also
susceptible to ROPV infection by using the athymic mouse xenograft
system and adult immunocompetent rabbits. Subrenal xenografts of
ROPV-infected rabbit vulvar and penile sheath tissues were strongly
positive for ROPV infection by histologic, in situ hybridization, and
Southern analyses. Direct inoculation of adult rabbit penises with
infectious ROPV produced small raised lesions of approximately 1 by 1 by 1 mm that were ROPV positive by both in situ hybridization and
Southern analyses and were also viral capsid antigen positive by
immunohistological staining. Infection of rabbit genital tissues with
ROPV may be a useful animal model for the study of genital
tissue-targeting papillomaviruses.
