Abstract
Papilloma virus infections in the genitoanal region are detectable by the demonstration of type-specific HPVDNA (DNA-DNA hybridization, in situ hybridization on cell smears) or by a peroxidase-antiperoxidase assay using formalin-fixed paraffin sections for demonstration of common structural antigens of papilloma viruses. Using these methods an epidemiological study on sexual partners with genitoanal papillomavirus infections has been initiated.
