本文用ELISA方法检测了30份母初乳中脊髓灰质炎病毒Ⅰ、Ⅱ、Ⅲ型、麻疹病毒及风疹病毒IgA抗体。结果显示,母乳中IgA抗体水平≥1:20的,脊髓灰质炎病毒Ⅰ、Ⅱ型均占86.7％,Ⅲ型占83.3％,麻疹病毒占66.7％,风疹病毒占60％。母乳中这些特异性抗体的存在,一方面反映了母亲粘膜所接触的抗原,可为病原体的流行病学研究提供依据;另一方面说明母乳喂养对保护婴儿免于感染有着重要意义。
In this paper, 30 samples of poliovirus type Ⅰ, Ⅱ, Ⅲ, measles virus and rubella virus IgA in colostrum were detected by ELISA. The results showed that the level of IgA antibody in breast milk was 1: 20, the poliovirus types Ⅰ and Ⅱ accounted for 86.7%, the type Ⅲ accounted for 83.3%, the measles virus accounted for 66.7% and the rubella virus 60%. The presence of these specific antibodies in breast milk, on the one hand, reflects the antigen contacted by the mucosa of the mother and provides a basis for the epidemiological study of pathogens. On the other hand, breastfeeding is of great importance in protecting infants from infection.
