| Outline of Final Research Achievements |
From the specimens of male urethritis, many kinds of microorganisms are detected, but the pathogenicities of microorganisms except for N. gonorrhoeae or C. trachomatis has not been determined.
As the new approach, the clone library method was used for analysis of microorganisms of urethritis. This method added quantitative concept to qualitative PCR methods. By this method, the pathogenicities of N. gonorrhoeae adn M. genitalium to the male urethra was confirmed. In addition, it was found that H. influenzae and N. meningitidis would be possible pathogens for male urethritis.
By the examination of microorganisms in the oral cavities of patients with male urethritis, it was found that causative bacteria of male urethritis and bacteria of the resident flora in the vagina were detected in the oral cavities of male patients. these indicated that oral sex is closely related to STIs. When we treat male urethritis, we have to eradicate microorganisms in both the urethra and oral cavities.
