Chironomids, of which approximately 10,000 species exist, are reported to cause severe immediate type allergic diseases in man. In the present study, immunological cross-reactivity between 14 chironomid species from different continents was proven by RAST inhibition, double immunodiffusion and a new allergoprint technique, based upon PAGE separation of insect crude extracts. Using isolated chironomid haemoglobins and sera of sensitized persons, as well as rabbit antibodies against larval crude extract or against the haemoglobin fraction of Chironomus thummi, it could be proven that cross-reactivity derives at least predominantly from haemoglobin components with common antigenic determinants in the different species.
摇蚊约有10000个种类,据报道可在人类中引发严重的速发型变态反应性疾病。在本研究中,基于昆虫粗提物的聚丙烯酰胺凝胶电泳分离,通过放射变应原吸附试验抑制、双向免疫扩散及一种新的变应原印记技术,证实了来自不同大陆的14种摇蚊之间存在免疫交叉反应。利用分离出的摇蚊血红蛋白、致敏者血清以及针对摇蚊幼虫粗提物或摇蚊血红蛋白组分的兔抗体,可证明交叉反应至少主要源自不同种类中具有共同抗原决定簇的血红蛋白成分。
