Study on nongonococcal genitourinary tract infections and drug resistance of Mycoplasma to antibiotics

Objective To compare the isolation rate of Ureaplasma urealyticum(Uu), Mycoplasma hominis(Mh) and Chlamydia trachomatis(CT), and to analyze the resistance of Mh and Uu to 6 kinds of antibiotics. Methods CT in genitourinary tract of 1 059 NGU patients was detected by kit of VIDAS. Uu and Mh in genitourinary tract was detected by kit of IST. Results From 1 059 tested samples, the total positive percentage for Mycoplasma and Chlamydia was 36.3% and 5.6% respectively, 14.8% and 3.7% for Mycoplasma and Chlamydia from male samples, 52.6% and 7.2% for Mycoplasma and Chlamydia from female samples. The colony counting result showed that the number of female samples with colonies more than 104 cfu/ml was greater than that of male samples, 73.2% versus 60.3% for Uu and 30.5% versus 25% for Mh. The sensitivity of Mycoplasma to antimicrobial agents was as follows from high to low: Pristinamycine, Doxycycline, Josamycin, Tetracycline, Ofloxacin, Erythromycin. Conclusions The isolation of Mycoplasma was more than that of Chlamydia from patients with genitourinary tract infection.Resistance monitoring of Mycoplasma periodically played an important role in clinical drug treatment.
