为了解本地区沙眼衣原体在临产前孕妇中的感染情况，我们自1995年2月至1996年2月，应用聚合酶扶反应（PCR）技术，采集宫颈分泌物，随机对3760例临产前孕妇进行了沙眼衣原体检测。结果发现阳性标本136例，阳性率为3．62％（136／3760），其中≥28周岁的临产前孕妇阳性率为3．65％（54／1480），＜28岁的临产前孕妇阳性率为3．60％（82／2280），≥28周岁与＜28周岁的临产前孕妇的检测结果，经x2检验上异无显著性（P＞0．05）。结果表明，对孕妇作沙眼衣原体（CT）筛查及治疗十分重要，是减少和阻断母婴传播的有效措施。
To understand the prevalence of Chlamydia trachomatis in prenatal pregnancies in our region, we collected cervical secretions from February 1995 to February 1996 using a polymerase chain reaction (PCR) technique and randomized 3760 prenatal pregnancies Chlamydia trachomatis detection. The positive results were found in 136 cases, the positive rate was 3.62% (136/3760). The positive rate of prenatal pregnant women≥28 years old was 3.65% (54/1480). The positive rate of prenatal pregnant women <28 years old Was 3.60% (82/2280), ≥28 years of age and <28 years of pre-labor pregnant women test results, by x2 test was no significant difference (P> 0.05). The results show that screening and treatment of pregnant women for Chlamydia trachomatis (CT) is very important, is to reduce and block the effective measures of mother-to-child transmission.
