DNA from oral tissue was amplified by seminested polymerase chain reaction. Fig. (1). This figure shows the amplicon of the second round reaction generating a 407 bp fragment on 2% agarose gel electrophoresis. Lane 1 is Marker 100 bp, lanes 2, 3, 4 and 5 are positive samples confirmed by nucleotide DNA sequencing, lane 6 is a negative sample. Lane 7 is the positive HPV control and lane 8 is the negative control. Some sequences of HPV types 6 and 31 were submitted to the DNA data Bank (GenBank http://www.ncbi.nlm.nih.gov/BLAST/) with the following accession numbers: DQ286926, DQ312262, DQ312263. The betaglobin gene was detected (data not shown) in all specimens to confirm the presence of amplificable DNA in the extracted specimens.
