目的：了解泌尿生殖道病原菌分布及支原体感染情况，进一步探讨支原体感染在性传播疾病中的重要性及体外药敏情况。方法：对１４４例因有泌尿生殖道系统症状而来就诊的门诊患者的尿道或宫颈分泌物，采用ＶｉｔｅｋＡＭＳ全自动微生物分析仪进行细菌鉴定，ＩＳＴ培养基进行支原体培养及药敏试验。结果：检出淋球菌７例（４９％），其他病原菌７０例（４８６％），支原体５３例（３６８％）。其中解脲支原体（ＵＵ）感染３５例（６６０％），人型支原体（ＭＨ）感染２例（３８％），ＵＵ＋ＭＨ混合感染１６例（３０２％），ＵＵ感染显著高于ＭＨ和ＭＨ＋ＵＵ混合感染（Ｐ＜００１）。结论：泌尿生殖道病原体感染以细菌为主，而支原体感染也占了较大比例，表明非淋菌性尿道炎已超过淋病而跃居首位，应引起临床极大重视。
Objective: To understand the distribution of genitourinary tract pathogens and mycoplasma infection, to further explore the importance of mycoplasma infection in sexually transmitted diseases and in vitro susceptibility. Methods: The urethral or cervical secretions of 144 outpatients with symptoms of genitourinary system were identified by VitekAMS automatic microbiological analyzer. Mycoplasma culture and drug sensitivity test were performed on IST medium. Results: Seven cases of Neisseria gonorrhoeae (49%), 70 (486%) of other pathogens and 53 cases of mycoplasma (368%) were detected. Among them, 35 cases (660%) were infected with UU, 2 cases (38%) were infected with human mycoplasma (MH), 16 cases (302%) were infected with UU + MH, the infection rate of UU was significantly higher than that of UU MH and MH + UU mixed infection (P <0 01). Conclusion: The genitourinary tract pathogens are mainly bacterial, while mycoplasma infection accounts for a large proportion, indicating that non-gonococcal urethritis has surpassed gonorrhea and leapt to the first place, which should arouse great attention in clinic.
