ABSTRACT
Urease conjugated enzyme linked immunosorbent assays (ELISA) were developed for the detection of human IgM and IgG antibodies against Mycoplasma pneumoniae. Results obtained by ELISA were compared with complement fixation test (CFT); which showed that of the 214 serum specimens tested, 80 were found to have antibody against M. pneumoniae. ELISA revealed that 70 of these specimens were IgG antibody, and 27 of them also contain IgM antibody. CFT failed to detect the presence of antibody against M. pneumoniae in five serum specimens tested. However, by using ELISA, three of them were found to have IgG and IgM antibodies. and the other two sera have IgG antibody only. Four out of the five specimens tested were the first serum specimens collected from patients with clinical and serological evidence of M. pneumoniae infection. In addition, 28 serum specimens, including 10 sera containing IgM rheumatoid factors and sera known to contain IgM antibody to other infectious organisms, were also tested for IgM antibody against M. pneumoniae by ELISA. None of these specimens showed a nonspecific reaction. ELISA had a sensitivity of 87.5% and a specificity of 96.3% when compared with CFT. Thus, ELISA developed in our laboratory is a specific test, and the results indicated that IgM ELISA might be used as a rapid diagnosis for M. pneumoniae infection.
