对313例孕妇进行了前瞻性调查分析。采用金色葡萄球菌A蛋白酶联免疫吸附试验,检查孕妇及胎儿脐血中抗弓形体抗体。孕妇感染率为32.9％(103/313)。农村与城市居民感染率分别为62.69％及30.06％。血清学检查阳性组中以往有异常孕产史者为6.79％,阴性组为0.47％,前者明显高于后者(P<0.01)。死胎发生率两组分别为6.79％及0.47％,前者明显高于后者(P<0.01),而胎儿畸形发生率两组中未见明显差异。
313 pregnant women were prospectively investigated. Staphylococcus aureus proteinase-linked immunosorbent assay was used to examine anti-Toxoplasma antibody in pregnant women and fetal cord blood. Maternal infection rate was 32.9% (103/313). Infection rates among rural residents and urban residents were 62.69% and 30.06% respectively. In the serologic positive group, the past history of abnormal pregnancy was 6.79% and the negative group was 0.47%, the former was significantly higher than the latter (P <0.01). The incidence of stillbirth in the two groups were 6.79% and 0.47%, respectively, the former was significantly higher than the latter (P <0.01), while the incidence of fetal malformations was no significant difference between the two groups.
