我们从培养的螺旋体中制备莱姆病病原体伯氏疏螺旋体的组分,并将其用作IgG抗体的酶联免疫吸附测定(ELISA)中的抗原。用含有表观分子量为34、39、59和68千道尔顿的主要蛋白质的提取物包被的聚苯乙烯板与用全细胞包被的板相比具有相当的灵敏度,但具有更高的特异性。在33份与B全细胞反应的莱姆病患者血清标本中,在类特异性ELISA中,当使用该提取物时,30个(91%)保持阳性。与密螺旋体抗体的交叉反应性极小。亚单位抗原的使用可能会提高莱姆病的血清学诊断。
We prepared fractions of Borrelia burgdorferi, the etiologic agent of Lyme disease, from cultured spirochetes and used them as antigen in an enzyme-linked immunosorbent assay (ELISA) for IgG antibody. Polystyrene plates coated with an extract containing major proteins with apparent molecular masses of 34, 39, 59, and 68 kilodaltons had comparable sensitivity but greater specificity than plates coated with whole cells. Of the 33 serum specimens from individuals with Lyme disease that reacted with whole cells of B. burgdorferi in the class-specific ELISA, 30 (91%) remained positive when this extract was used. Cross-reactivity was minimal with antibody to treponemes. Use of subunit antigens may improve serological diagnosis of Lyme disease.
