An enzyme-linked immunosorbent assay (ELISA) using a highly purified soluble antigen prepared from pathogenic Treponema pallidum (Nichols) was carried out to detect specific IgM antibodies in syphilis. Serum specimens from 365 patients with untreated or treated syphilis were tested by the ELISA and by the 19S(IgM) fluorescent treponemal antibody-absorbed test. In the ELISA sera were preabsorbed with aggregated human IgG to eliminate any rheumatoid factor present. Sera from 331 healthy blood donors served as controls. The results of both tests correlated well. The specificity and sensitivity of the treponemal ELISA were both greater than 97%. The assay was easy to perform and may be automated.
采用从致病性梅毒螺旋体(Nichols株)制备的高度纯化可溶性抗原进行酶联免疫吸附试验(ELISA),以检测梅毒特异性IgM抗体。用ELISA和19S(IgM)荧光密螺旋体抗体吸收试验检测了365例未经治疗或已治疗梅毒患者的血清标本。在ELISA中,血清先用聚集的人IgG预吸收,以消除任何存在的类风湿因子。331名健康献血者的血清作为对照。两种试验结果相关性良好。密螺旋体ELISA的特异性和敏感性均大于97%。该检测方法易于操作,且可实现自动化。
