Papillomaviruses of supergroup A exhibit genital tropism and are best known as etiologic agents for benign and malignant cervical lesions in women. A polymerase chain reaction direct sequencing approach with P-33-labeled dideoxynucleotides was used to detect and type human papillomaviruses (HPVs) in cervical biopsies. A novel sequence was found in condylomatous specimens from a human immunodeficiency virus-positive French Canadian woman. The viral gene L1 was sequenced completely, yielding a novel HPV type of supergroup A, named JC9710. This is related to a previously described HPV type from New Mexico, CP8061, and to Colobus monkey papillomavirus 1. Sequence similarity searches and phylogenetic analyses with different software packages clustered the three viral types as a new clade, for which the next available number, A15, was proposed.
