摘要
应用标记荧光素的抗沙眼衣原体（Ｃｔ）单克隆抗体，直接免疫荧光法（ＤＦＡ）检测了１７２４例泌尿生殖道标本，总Ｃｔ感染率为１９．４％，男性Ｃｔ感染率为１９．５％（１６０／８２２），女性Ｃｔ感染率为１９．４％（１７５／９０２）；选择符合诊断标准的男性非淋菌性尿道炎１３４例和男性淋菌性尿道炎８０例，检测Ｏ的阳性率分别为３５．８％和２５．Ｏ％。结果显示泌尿生殖道的Ｃｔ感染在我国存在，且构成流行，应引起高度重视。ＤＦＡ诊断Ｃｔ感染具有特异性强、敏感性高、简便快速等优点。
sing a fluoresceinlabelled monoclonal antibody against Chlainydia trachomatis(Ct),we have de-tected l 724 samples of genitouririary tract with the direct immunofluoroassay(DFA ).The total infec-tion rate of Ct was l9.4%,and the infection rates in male and female were l9.5%(160/822)and19.4%(175/902),respectively.In 134 samples of nongonococcal urethritis and 80 samples of gonococ-cal urethritis in male patients,the positive rates of Ct were 35.8%and 25.0%,respectively。 Our re-sults showed that the Ct infection in genitourinary tract existed and even prevailed in China and shouldbe taken care of seriously。 The direct immunofluoroassay was indicated as a specific,sensitive,simpleand rapid method for the diagnosis of Ct infection.
