PCR检测沙眼衣原体在诊断婴幼儿肺炎上的应用

The Test of Chlamydia Tracchomatis by Using PCR Helps in the Diagnosis of Infant Pneumonia

对１９９５年１月～５月收治的９５例肺炎患儿采用聚合酶链反应（ＰＣＲ）方法对婴幼儿的鼻咽部分泌物进行沙眼衣原体（ＣＴ）检测，结果阳性１８例（１８．９％），其中３月以内婴儿３０．６％，～６月２２％，～１岁１５％，～４岁４％。可见ＣＴ肺炎以６个月以下最多见。临床表现大多起病缓慢，一般情况尚好，以呼吸增快，阵发性咳嗽为主，病程１４～４０天。１８例中有１０例伴有结膜炎，１２例为产道分娩。

At present,three are few reports that crlamydia thachomatis(CT) can cause pneumonia in our country. We collected pharynx nasal secretion samples from all the patients for CT test from 1995, 01～1995, 05 by using PCR method.The result showed that 18 samples were positive for CT,among them 30.6% were below 3 months old,22%;3 months～6 months,15%;6 months-1 year,4%;1 year～4 years. This result suggests that infant pneumonia cansed by CT mainly exists in infant below 6 months.Clinic detum demonstrated that many of them had a slow clinic process and the general condition were good, and then followed by breathing fast coughing by fits.All the patients were cured after a course of 14 days～40 days inthese 18 cases,10 patients Were companied with conjunctivitis and 12 patients were delivered through vagina tract.
