摘要： 目的 对我国部分地区不同类型的性病人群进行生殖支原体(Mg)感染状况检测分析,以明确Mg感染在非淋菌性尿道炎中的可能致病作用。方法 采用两对引物的聚合酶链反应技术,根据Mg粘附蛋白基因及支原体种属内核糖体基因序列设计引物,收集广东、昆明、上海、南京、常州等地性病门诊和(或)性罪错者的泌尿生殖道分泌物标本。结果 性病高危人群的Mg-DNA检出率明显高于正常体检组(χ2=7822,P<001),其中广东性病门诊及昆明性罪错人群的Mg-DNA检出率明显高于南京、上海、常州等地两种人群的检出率(χ2=8536,P<001及χ2=5885,P<005).未查到其他相关病原体者亦可查及Mg-DNA;有Mg感染者亦可同时感染其他微生物,如衣原体、解脲支原体等;有尿道炎症状病例中Mg-DNA的检出率高于无尿道炎症状者(χ2=11667,P<001).结论 性病高危人群中存在生殖支原体的感染,在不同地区不同类型人群组中Mg感染率有一定差异。

Abstract: Objective To detect Mycoplasma Genitalium (Mg) infection in high risk populations of STDs from six cities in China and try to clarify the possible role of Mg in the pathogenesis of non-gonococcal urethritis.Methods Polymerase chain reaction (PCR) technique based on 2 pairs of primer for Mg-Pa(adhesion protein) and 16S-rRNA (Mycoplasma genera) was used to detect Mg infection. Urogenital specimens of different high risk populations or urethritis patients of STDs were collected from Guangdong, Kunming, Shanghai, Nanjing, and Changzhou areas. Results The positive detection rate of Mg-DNA in high risk populations of STDs was significantly higher than that of normal group(χ2=7.822, P<0.01). The positive detection rates in STD clinics from Guangdong and promiscuous persons from Kunming were higher than those detected from Shanghai, Nanjing and Changzhou areas(χ2=8.536, P<0.01 and χ2=5.885,P<0.05) Mg-DNA could be detected in those patients without other relevant pathogens. Some patients simultaneously infected both Mg and other microbes, such as Chlamydia trachomatis and/or Ureaplasma urealyticum. The positive Mg-DNA detection rate in patients with urethritis symptoms was higher than that without the symptoms (χ2=11.667, P<0.01).Conclusion Mg infection exists in high risk populations of STDs in China, and Mg infection rate is different among different high risk groups.
