RESUMEN
<p><b>OBJECTIVE</b>To detect and type human papilloma virus (HPV) in the warts of oral mucosa from HIV-positive patients, and better understand the biological characters of these oral warts.</p><p><b>METHODS</b>Polymerase chain reaction (PCR) was used to detect and type HPV infection by consensus HPV primers Gp5+/Gp6+ and specific HPV primers (HPV6/11, 16, 18, 31, 33) in 34 cases of oral mucosa warts from HIV-positive patients.</p><p><b>RESULTS</b>The HPV infection rate was 88.2% by consensus HPV primers Gp5+/Gp6+; the HPV infection rate of HPV6/11, 16, 18, 31 was respectively 47.06%, 11.67%; 2.94%, and 5.88% by specific HPV primers.</p><p><b>CONCLUSION</b>Most lesions of oral warts from HIV-positive patients are associated with the infection of HPV. The low risk HPV6/11 infection is more common than the high risk HPV16, 18, 31.</p>
