Papillomavirus genomes in experimentally induced fibromas in white-tailed deer

Cutaneous fibromas of white-tailed deer were transmitted successfully to 5 young deer. Serial biopsy specimens of the induced lesions were analyzed for white-tailed deer papillomavirus, using Southern blot hybridization. Viral genomes were found in all specimens taken 1 to 7 weeks after inoculation and, in some cases, from specimens of the inoculation site obtained later. Viral DNA was found before histologic evidence of fibroblast proliferation and persisted in low copy number, compared with viral DNA of naturally developing fibromas.
