Two intraperitoneal injections of either infectious or non-infectious rabbit papilloma suspensions actively immunize rabbits against papillomatosis. The capacity of the non-infectious suspensions to immunize is considered as evidence that they contain papilloma virus even though none can be demonstrated by the usual infection test.

objective(s): to investigate the expression of human papilloma virus (hpv) l1 capsid protein, and human telomerase rna component (hterc) in cervical cancer and the role of detection of both genes in screening of cervical cancer.   materials and methods: a total of 309 patients were recruited and cervical exfoliated cells were collected. immunocytochemistry was employed to detect hpv l1 capsid p...

Viruses are the accepted cause of many important cancers including cancers of the cervix and anogenital area, the liver, some lymphomas, head and neck cancers and indirectly human immunodeficiency virus associated cancers. For over 50 years, there have been serious attempts to identify viruses which may have a role in breast cancer. Despite these efforts, the establishment of conclusive evidenc...

Human papilloma virus (HPV) was isolated from red plaques of a patient (N. F.) with epidermodysplasia verruciformis. Elec tron microscopic examination showed characteristic particles of papilloma virus as ¡cosahedrons about 45 nm in diameter. DNA was extracted from these particles, and closed-circular DNA (Form I) was purified by centrifugation in CsCI containing ethidium bromide. The molecula...
