Analysis of mycoplasma infection and drug susceptibility in 6 573 patients with nongonococcal urethritis

Objective To investigate the infection status and drug suscepetibility of mycoplasma from 6 573 patients with nongonococcal urethritis, and to provide the scientific bases for the clinical application of antibiotics. Methods Mycoplasma detection kit was used to detect ureaplasma urealyticum (Uu) and mycoplasma hominis (Mh) and the drug susceptibility. All the patients were divided into two groups: Chinese group and foreigner group. Results Among 5 675 Chinese patients, 2 985 patients were infected by mycoplasma (52.6%). The infection rate of Uu was 2 312 (40.7%). 35.2% patients were male, and 61.4% patients were female. In 898 foreign patients, 440 patients were infected by mycoplasma (49.0%). The infection rate of Uu was 327 (36.4%). 32.2% patients were male, and 59.5% patients were female. In Chinese patients infected by Uu, the susceptibility rates to MIN, DOX, JOS and CLA were 96.7%, 96.2%, 93.7%, 89.7%, respectively. In foreign patients, the susceptibility rates to MIN, DOX, JOS, and CLA were 98.9%, 98.4
