淋球菌、支原体和沙眼衣原体在慢性前列腺炎中的感染分布及耐药性分析

目的 :了解淋球菌、支原体和沙眼衣原体在慢性前列腺炎中的感染分布和耐药情况。方法 :用培养法对淋球菌和支原体进行分离鉴定和药敏试验 ,用头孢硝噻吩法对淋球菌进行 β 内酰胺酶检测 ,用单克隆抗体胶体金标法测定沙眼衣原体。结果 :在 2 90 0份前列腺液标本中 ,淋球菌、支原体和沙眼衣原体的分离率分别为3.3 %,12 .8%和 0 .9%。淋球菌 β 内酰胺酶的产生率为 12 .6 %,淋球菌对青霉素的耐药率为 73.7%,对氧氟沙星和环丙沙星的耐药率均为 91.6 %,对壮观霉素和头孢菌素的敏感性均较高。支原体对四环素、乙酰螺旋霉素、红霉素和氧氟沙星的耐药率均达到或超过 5 0 .0 %,而罗红霉素、强力霉素、左旋氧氟沙星、美满霉素、交沙霉素和阿奇霉素的敏感率均达 70 .0 %～ 80 .0 %。结论 :支原体在慢性前列腺炎中的分离率高于淋球菌和沙眼衣原体。监测淋球菌和支原体的耐药性对指导临床合理使用抗生素有重要意义。

Infectious distribution and resistant of Neisseria gonorrhoeae,Mycoplasma, and Chlamydia trachomatis in the chronic prostatitis

Objective To investigate the infectious distribution and resistant of Neisseria gonorrhoeae,Mycoplasma,and Chlamydia trachomatis in the chronic prostatitis. Methods The identification and susceptibility of Neisseria gonorrhoeaes and Mycoplasmas were detected by a cultural method. The nitrocefin test was uesd to detect the β-lactamase in Neisseria gonorrhoeae strains. Chlamydia trachomatis was identificated by a monoclonal gold labeled antibody method. Results A total of 2 900 prostatic fluids were detected and the rates of isolation of Neisseria gonorrhoeae, Mycoplasma, and Chlamydia trachomatis were 3.3%, 12.8%, and 0.9%, respectively. The prevalence of β-lactamase in Neisseria gonorrhoeae strains was 12.6%. The resistant percentages of Neisseria gonorrhoeae strains were 73.7% to penicillin and 91.6% to ciprofloxacin and ofloxacin respectively, but the susceptibility to spectinomycin, cephalosporin and cefoxitin was good. The resistant rates of Mycoplasma to tetracycline, acetylspiramycin, erythromycin, and ofloxacin were 50.0% or more, but the susceptibilities to roxithromycin, doxycyclin, levofloxacin, minocyclin, josamycin, and azithromycin were about 70.0%～80.0%. Conclusion The isolation rate of Mycoplasma is higher than that of Neisseria gonorrhoeae and Chlamydia trachomatis in the chronic prostatitis. It is important to detect the susceptibility of Neisseria gonorrhoeae and Mycoplasma for the use of antibiotics in reason.
