[The study of Neisseria gonorrhoeae, Chlamydia trachomatis, Ureaplasma urealyticum infection status by polymerase chain reaction].

The study involved 355 specimens of STD clinic patients collected from Beijing, Shantou and Wuhan, for the detection of Neisseria gonorrhoeae, Chlamydia trachomatis, Ureaplasma urealyticum by polymerase chain reaction. The results showed that the positive rate of Neisseria gonorrhoeae being the highest in the patients attending STD clinics from the three cities. The detection rate of Neisseria gonorrhoeae in male patients was higher than in females. The positive rates of Chlamydia trachomatis and Ureaplasma urealyticum in the three cities differed from each other greatly.
