ABSTRACT
Objective To investigate the infection of HPV subtypes in male urethra in Xi'an area.Methods The eighteen subtypes of HPV DNA were detected in 478 cases of male patients by PCR-reverse dot hybridization assay (RDB) including low risk subtypes (HPV6,11,43) and high risk subtypes (HPV16,18,31,33) during 2015～2016.Results The total infection rate of HPV subtypes in 478 subjects was 44.97％ (215/478).The percents of subjects infected by one subtype,two ones,three ones,four ones and five ones were 32.85％ (157/478),8.79％ (42/478),2.09％ (10/478),0.42％ (2/478) and 0.84％ (4/478),respectively.The detection rates of low risk subtypes and high risk ones were 40.17％ and 22.38％ in which the most common subtypes were HPV6 (24.69％),HPV11 (12.13％),HPV16 (5.65％),HPV43 (3.35％) and HPV52 (2.30％) and those of others were from 0％ to 2.09％.The infection pattern of HPV subtypes gave priority to one subtype infection in all age groups.There was statistically different between H PVs (6,11,16,43,52,66) in twenty years or older subjects (x2 =12.879～109.7,P=0.000～0.025).Conclusion The majority of HPV subtypes detected in male urethra were HPV6,HPV11,HPV16,HPV43 and HPV52 in Xi'an area which provided epidemiological data for HPV infection in males.
