Phylogenetic tree constructed from Hungarian HPV 33 LCR sequences reported in the current study and from overlapping HPV 33 LCR sequences (Chen et al., 2011) from the GenBank database. The bootstrap consensus tree shown was constructed using the maximum likelihood (ML) method. The Hungarian isolates are indicated by black circles. Reference intratype variant isolates are indicated by arrows. Only one isolate is included from each Hungarian variant. Bootstrap values equal to or higher than 57% are shown next to the branches
