应用套式聚合酶链反应技术对４１０ 例晚期妊娠妇女的宫颈分泌物及８６ 例羊水与新生儿咽部分泌物进行生殖支原体（ Ｍｇ 检测），观察并分析Ｍｇ 的母婴传播情况及对母婴的影响。结果：宫颈Ｍｇ 阳性率为７－８０ ％ ，与孕妇的年龄、文化程度及胎产次无关（Ｐ＞ ０－０５）。宫颈Ｍｇ 阳性组羊水及新生儿检出率分别为１２－５０％ 与１８－７５ ％ ，明显高于对照组（Ｐ＜ ０－０５ ；０－０１）。两组胎膜早破、早产及低体重儿发生率的比较差异有显著性（Ｐ＜ ０－０１ ，０－０５；０－０５） ，而ＩＵＧＲ、新生儿窒息、新生儿畸形、新生儿肺炎、产后出血及产褥热的发生率比较无差异（Ｐ＜ ０－０５） 。提示：晚期妊娠妇女下生殖道Ｍｇ 感染可以垂直传播并与胎膜早破、早产及低体重儿的发生有关。
The cervical secretions of 410 pregnant women and 86 cases of amniotic fluid and neonates pharyngeal secretions were tested for mycoplasma genitalium (Mg) by nested polymerase chain reaction (PCR). The mother-to-child transmission of Mg Impact. Results: The positive rate of cervical Mg was 7-80%, unrelated to pregnant women ’s age, education and birth order (P> 0-05). The detection rates of amniotic fluid and neonates in cervical Mg positive group were 12-50% and 18-75%, respectively, which were significantly higher than those in control group (P <0-05; 0-01). The incidence of premature rupture of membranes, premature birth and low birth weight babies were significantly different between the two groups (P <0-01, 0-05; 0-05), while IUGR, neonatal asphyxia, neonatal malformation, neonatal pneumonia There was no difference in the incidence of postpartum hemorrhage and puerperal fever (P <0-05). Tip: Late pregnancy, lower genital tract infection in pregnant women can spread vertically and premature rupture of membranes, premature birth and low birth weight infants.
