An enzyme linked immunosorbent assay (ELISA) to measure free serum IgA antibodies to Pseudomonas aeruginosa in patients with cystic fibrosis is described. Results were reproducible and there was no interference from crossreacting antibodies directed against other Gram negative bacteria. Titres were high in patients with Pseudomonas aeruginosa infection and differed according to the stage of the infection. These preliminary results suggest that this assay may be of value in assessing the state of Pseudomonas aeruginosa infection in patients with cystic fibrosis.
本文描述了一种用于测量囊性纤维化患者血清中抗铜绿假单胞菌游离IgA抗体的酶联免疫吸附测定(ELISA)。结果具有可重复性,且不存在针对其他革兰氏阴性菌的交叉反应抗体的干扰。铜绿假单胞菌感染患者的抗体滴度较高,且根据感染阶段有所不同。这些初步结果表明,该测定法可能有助于评估囊性纤维化患者铜绿假单胞菌感染的状况。
