Abstract
Simple assays which reliably distinguish between past infection with Chlamydia pneumoniae and with Chlamydia trachomatis are needed. We developed an enzyme-linked immunosorbent assay (ELISA) for this purpose by reducing antigen cross reactive lipopolysaccharide epitopes with deoxycholate treatment and releasing antibodies of low affinity with a 6 M urea wash step. Paired serum samples from 212 patients with non-C. pneumoniae-associated community acquired pneumonia and single serum samples from 61 healthy students, 61 women with gynaecological complaints, and 100 blood donors were tested in the assay system. Excellent positive/negative correlation with the microimmunofluorescence (MIF) test was shown. This urea ELISA assay may be useful in assessment of past infection with these organisms, especially in epidemiological studies.
