Neighbor joining phylogenetic tree generated using nucleotide sequences of the HPV16 L1 gene. Legend: Study sequences are labeled in dots, others without dots are reference strain, including: A1 (K02178), A2 (AF536179), A3 (HQ644236), A4 (AF534061 and LC368960), B1 (AF536180), B2 (HQ644298), C (AF472509), D1 (HQ644257), D2 (AY686579), D3 (AF402678). Phylogenetic trees were constructed by the Neighbor-Joining method and the Kimura 2-parameter model by MEGA 6.0 package. Only bootstrap values above 50% are displayed in the branches
