Study of Mycoplasma Infection and Drug Susceptibility Testing in Male Venereal Patients with Manifestation of Urethritis

Objective:To observe the infection and drug resistance of mycoplasma in male venereal patients. Methods:To the samples of 5 354 patients who were suspected of venereal diseases, Neisseria gonorrhoeae culture, mycoplasma culture and drug susceptisility testing were done. Results:In these patients, the positive rate of pathogen was 24.9%(1 333/5 354). Among them, the proportion of neisseria gonorrhoeae, chlamydi trachomatis (Ct), ureaplasma urtalyticum (Uu), mycoplasma hominis (Mh) and Uu confirmed with Mh was 5.0%(67/1 333), 31.4% (418/1 333), 57.2%(763/1 333), 6.4%(85/1 333) and 9.1%(121/ 1 333) respectively. The result of drug susceptibility testing indicated that 54.7% was Ofloxacine resistance, 44.9% was erythromycine, 19.9% was tetracycline, 19.6% was doxycycline, 15.6% was josamycine and 11.6% was pristinamycine one. Conclusion:In male venereal patients manifestation of urethritis, Uu was the major pathogen. Most of venereal patients was between 21 and 40. Drug resistance of mycoplasma was severe. Culture and drug susceptibility testing of mycoplasma were important for clinical therapy.
