| identification of a unique group of human papillomavirus type 16 sequence variants among clinical isolates from barbados. | the naturally occurring sequence variation of human papillomavirus type 16 (hpv-16) was analysed by direct sequence analysis of the pcr products of the long control region (lcr), the e5 and e7 open reading frames (orfs), a segment of the l2 orf overlapping the early viral poly(a) signal and a small segment of the l1 orf or clinical isolates from barbados and the netherlands. despite the widely different geographical and ethnic origin of the two groups of specimens, sequence analysis revealed rel ... | 1994 | 8077948 |
