Detection and susceptibility to antibiotics of Mycoplasma in genitourinary tract during 2000~2004 / 解放军医学杂志

ABSTRACT

Objective To investigate infection rate and susceptibility to antimicrobial agents of Mycoplasma urealyticum and Mycoplasma hominis in the genitourinary tract, and to provide a reference for clinical diagnosis and therapy. Methods Genitourinary secretions were collected with swabs. They were cultured with the diagnostic kit of Mycoplasma (Biomerieux Company) to detect M. urealyticum and M. hominis. Meanwhile the susceptibility of Mycoplasma against 9 antimicrobial agents was tested with the same kit. According to the manual of the kit, the results were read. The data were statistically analyzed with WHONET5.1 and SPSS. Results A total of 1 008 samples were collected, and the positive rate was 77.5%. Among 781 positive cases of Mycoplasma, 572 were M. urealyticum(56.0%), 40 were M. hominis (4.0%), and 169 were M. urealyticum combined with M. hominis (16.7%). The susceptibility rate of M. urealyticum to Doxycycline, Josamycin, Ofloxacin, Erythromycin, Tetracycline, Ciprofloxacin, Azithromycin, Clamycin and Pristinamycin was 89.3%, 95.1%, 17.5%, 64.3%, 84.1%, 14.8%, 77.8%, 90.8% and 96.5%, respectively. The susceptibility rate of M. hominis to the above drugs was 86.0%, 78.9%, 23.2%, 0, 73.2%, 57.1%, 0, 7.7% and 83.9%, respectively. The resistant rate of Mycoplasma to Azithromycin and Clamycin in 2004 was higher than that during the period of 2000 to 2003(P
