摘要
用所建立的沙眼衣原体质粒引物聚合酶链反应技术(PCR)检测116例泌尿生殖道沙眼衣原体,并与直接免疫荧光法(DIFA)进行比较。结果PCR阳性38例,DIFA阳性的32例中有31例PCR阳性。PCR敏感性为96.9%,特异性为91.7%。PCR阳性者于治疗结束1~2周后复诊21例,其中4例PCR仍然阳性。结果显示,PCR可快速、敏感、特异地检测泌尿生殖道沙眼衣原体DNA,然而对治疗后短期内复诊患者,似乎不宜仅以PCR阳性结果作为重复治疗的依据。
s A plasmid derived polymerase chain reaction(PCR) assay was developed for the detection of chlamydia trachomatis in urogenital specimens of 116 patient,and the results were compared with that DIFA.33 cases were PCR positive,and Ct DNA were detected in 31 of the 32 cases positive by DIFA.The sensitivity and specificity of PCR were 96.9% and 91.7%,respectively .21 cases positive by pretreatment PCR assay were followed up in 1-2 weeks after the completion of treatment,and 4 of them were still PCR positive.The results show that PCR is a rapid,sensitive and specific diagnostic tool for Ct DNA,however,it seems less appropriate to use PCR positive results as indicators to give repetitive medications for patients shortly after treatments.
