弓形体感染与垂直传播

The Vertical Transmission and Toxoplasma Infection

目的了解孕妇弓形体感染率、易感染因素及垂直传播的可能性。方法采用间接血凝实验(IHA)及酶联免疫吸附实验(ELISA)两种方法对保定市郊1742名孕妇进行了弓形体血清学检测。结果1742名孕妇抗体阳性者167人,感染率9.59%,弓形体感染与流产、早产、死胎、畸形(统称异常妊娠)有密切关系,妊娠早期和晚期对胎儿的影响不一样,与猫、狗、猪、羊等动物有密切接触史、食生肉史对孕妇血清学检测阳性率有影响。孕妇感染率随年龄增大而升高。结论保定市郊孕妇存在弓形体感染,感染会造成异常妊娠,感染率高低与动物接触史、食生肉史有关。

Objective： To understand the probability of toxoplasma infection among pregnant women, susceptible to some factors and vertical transmission. Methods： We examined blood toxoplasmatic antibodies with IHA and ELISA among 1742 pregnant women lived in BanDing.
