１９９０年７月—１９９３年９月，我们应用捕获酶免疫和酶联免疫吸附试验，对河南省六地市数千名孕妇进行了多种传染的血清抗体联合监测。其结果：弓形体、风疹、巨细胸病毒的ＩｇＭ抗体阳性率分别为３．３４％（１３８／４１２６）、０．８４％（６２／７３７５）、１．１０％（７１／６４２８），布氏菌ＩｇＧ抗体阳性率为０．９２％（３８／４１２６）。监测发现：孕妇血清抗体阳性率与其年龄、孕期、孕次无关；而不同地区、不同季节的孕妇血清抗体阳性率有一定差异；除布氏菌外，其它三种血清抗体阳性率与孕妇职业无关。同时发现：三次监测的３０９例阳性孕妇中，其交叉感染率为１．６１％。上述结果对进一步开展畸形儿的出生干预具有重要的指导意义。
July 1990-September 1993, we used capture enzyme-linked immunosorbent assay and enzyme-linked immunosorbent assay (ELISA) to monitor the joint transmission of several kinds of serum antibodies to thousands of pregnant women in six cities in Henan Province. The results showed that the positive rates of IgM antibodies to T. gonorrhoeae, rubella and giant and thorax viruses were 3.34% (138/4126), 0.84% (62/7375), 1.10% (71/6428) The positive rate of bacterial IgG antibody was 0.92% (38/4126). Monitoring found that: the positive rate of serum antibody in pregnant women has nothing to do with their age, pregnancy and pregnancy times; while in different regions and seasons, there is a certain difference in the positive rate of serum antibody among pregnant women; except for Brucella, the positive rate of the other three serum antibodies has nothing to do with pregnant women’s occupation . Also found that: three monitoring of 309 cases of positive pregnant women, the cross-infection rate was 1.61%. The above results have important guiding significance for further carrying out birth intervention for deformity children.
