^a In bold case HPV genotypes defined by IARC working group as class I carcinogens for humans [5,50].
^b HPV genotypes present in multiple infections were characterized by subcloning of MY09/MY11 (two samples) or GP5+/GP6+ (three samples) PCR products and sequencing analysis. Number of clones analyzed for each HPV genotype are given in parenthesis.
