摘要
采用纯化的腺病毒抗原包被固相载体以辣根过氧化物酶标记的抗人ＩｇＡ结合物作为第二抗体，建立了腺病毒ＩｇＡＥＬＩＳＡ检测法，对４１例患儿血清进行了检测，腺病毒ＩｇＡ阳性率为３９０％，正常儿童为３２％，指出腺病毒仍是婴幼儿呼吸道感染的重要原因之一。
The detection method for adenovirus specific IgA antibody was established with purified adenovirus antigen to coat solid microplate and anti_human IgA as second antibody. The results showed that the positive rate of adenovirus IgA is 39.0% in infants infacted respiratory virus, but the rate is 3.2% in healthy children. This indicates that the adenovirus is a main pathogen in respiratory infection in children. This method is specific sensitive, simple and realiable.
