title: Evidence of prevalent genital-type human papillomavirus infections in adults and children.
abstract: Recombinant proteins encoded by the E2, E7, L1, and L2 open reading frames (ORF) of human papillomavirus (HPV) types 6b, 16, and 18 were used in Western blot assays to detect serum IgG antibodies in women attending a sexually transmitted diseases clinic (n = 92) and in hospitalized children (n = 81). Antibodies to late gene products (L1 or L2 ORF) were more common than antibodies to early gene products (E2 or E7), both in the adults and the children; overall, the antibody prevalences in the children and the sexually active adults were not significantly different. Human sera with high titers of antibodies to the HPV16 E7 recombinant protein immunoprecipitated the genuine HPV16 E7 protein from the cervical carcinoma cell line CaSki. As an independent measure of HPV infection, the polymerase chain reaction was used to detect HPV6b and HPV16 in oral mucosal scrapings from adults (n = 35) and preschool children (n = 21). In adults, HPV6b and HPV16 DNA were detected in 17% and 23% of oral mucosal samples, respectively. In preschool children, HPV6b and HPV16 DNA were found in 24% and 19% of oral samples, respectively.
