Prevalence and drug tolerance of mycoplasma in patients with urogenital inflammation / 中华男科学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To observe the prevalence and drug tolerance of mycoplasma(Ureaplasma urealyticum and Mycoplasma hominis) in patients with urogenital inflammation.</p><p><b>METHODS</b>Three thousand and fifty-five patients with urogenital inflammation such as non-gonococcal urethritis(NGU), chronic prostatitis or pelvic inflammation from 1999 to 2003 were included. The results of mycoplasma culture and drug sensitivity test were analyzed.</p><p><b>RESULTS</b>A total of 992(32.5%) cases were mycoplasma positive in the 3,055 patients, and there was no significant difference in the yearly positive percentage in the 5 years (P < 0.05). Among them, 701(70.7%) were infected with Ureaplasma urealyticum, 44(4.4%) with Mycoplasma hominis, and 247(24.9%) with both Ureaplasma urealyticum and Mycoplasma hominis, the Ureaplasma urealyticum infection rate being much higher than that of Mycoplasma hominis and mixed infection (P < 0.01). The high colony counting(> or = 10(4) cfu/ml) in Ureaplasma urealyticum infection patients accounted for 76.7%, while Mycoplasma hominis infection represented only 18.2%. The results of drug tolerance test showed a higher sensitivity to doxycycline, pristinamycin, josamycin and tetracycline (94.3%, 96.6%, 86.5% and 97.4% respectively), and a lower sensitivity to erythromycin and ofloxacin (54.8% and 29.4% respectively).</p><p><b>CONCLUSIONS</b>Ureaplasma urealyticum and Mycoplasma hominis should be detected simultaneously and the drug tolerance test is needed for the selection of appropriate antibiotics.</p>
