title: Use of quantitative and objective enzyme immunoassays to investigate the possible association between Chlamydia pneumoniae and Mycoplasma pneumoniae antibodies and asthma.
abstract: Sera from 150 consecutive patients with established asthma and 150 matched controls were examined for Chlamydia pneumoniae IgG and IgA with commercially available enzyme immunoassays (EIAs) detecting immune response solely to surface proteins of elementary bodies. The assays were also modified to measure combined immune response to surface proteins and family-specific lipopolysaccharide antigen. Mycoplasma pneumoniae IgG and IgA were measured with new commercial EIAs utilising P1-enriched protein fraction as an antigen. No statistically significant differences between the patient groups in terms of prevalence or levels of antibodies to either organism were found with these methods.
