The control of sexually transmitted diseases (STDs) in remote rural communities would be enhanced by a sensitive self-administered method for the detection of asymptomatic infection. Results of conventional methods for the detection of STDs were compared with results of tampon-collected specimens analyzed by polymerase chain reaction (PCR) for 480 women. Neisseria gonorrhoeae, Chlamydia trachomatis, and Trichomonas vaginalis were detected by routine methods in 4 (1%), 14 (3%), and 41 (9%) samples, respectively, while PCR detected these organisms from 52 (11%), 26 (5%), and 75 (16%) tampons, respectively. The detection of each organism was significantly greater by PCR in tampon-collected samples than by routine conventional methods (P < .01). Discrepant results were confirmed by separate primers in 40 of 48 specimens for N. gonorrhoeae, in 11 of 12 specimens for C. trachomatis, and in 31 of 32 specimens for T. vaginalis. Tampons tested by PCR provide an acceptable and sensitive method for detection of STDs in women living in remote areas.
一种灵敏的自我检测方法可用于检测无症状感染,这将有助于加强偏远农村社区性传播疾病(STD)的防控。研究人员将480名女性的常规性传播疾病检测结果与通过聚合酶链反应(PCR)分析棉塞采集样本的结果进行了比较。通过常规方法检测到淋病奈瑟菌、沙眼衣原体和阴道毛滴虫的样本分别为4份(1%)、14份(3%)和41份(9%),而PCR分别从52份(11%)、26份(5%)和75份(16%)棉塞中检测到了这些病原体。在棉塞采集的样本中,通过PCR检测到的每种病原体数量均显著高于常规方法(P < 0.01)。48份淋病奈瑟菌样本中的40份、12份沙眼衣原体样本中的11份以及32份阴道毛滴虫样本中的31份,通过单独引物证实了结果存在差异。通过PCR检测棉塞为偏远地区女性性传播疾病的检测提供了一种可接受且灵敏的方法。
