Antibodies against Mycoplasma pneumoniae antigen obtained by Tween-ether treatment from purified M. pneumoniae were measured by means of enzyme-linked immunosorbent assay (ELISA). Paired sera from 19 patients with pneumonia and from 13 patients with acute pancreatitis with a significant rise in complement fixing antibodies against M. pneumoniae were studied. Single sera from healthy 1-year-old children were used as controls. High levels of IgG and IgM class antibodies were seen in sera from patients with pneumonia while most patients with acute pancreatitis and all the children showed low levels of antibodies. The results indicate that ELISA using Tween-ether treated M. pneumoniae antigen could be used successfully in the specific laboratory diagnosis of M. pneumoniae infection.
采用酶联免疫吸附测定法(ELISA)检测了经吐温 - 乙醚处理从纯化的肺炎支原体获得的抗肺炎支原体抗原的抗体。研究了19例肺炎患者和13例急性胰腺炎患者的配对血清,这些患者针对肺炎支原体的补体结合抗体显著升高。将1岁健康儿童的单份血清用作对照。肺炎患者血清中可见高水平的IgG和IgM类抗体,而大多数急性胰腺炎患者和所有儿童的抗体水平较低。结果表明,使用经吐温 - 乙醚处理的肺炎支原体抗原的ELISA可成功用于肺炎支原体感染的特异性实验室诊断。
