A newly developed enzyme immunoassay (EIA) was used to detect the
presence of pneumococcal teichoic and lipoteichoic acids in
cerebrospinal fluid (CSF) from patients with Streptococcus pneumoniae meningitis who were being treated with antibiotics. All initial CSF samples, which on culture grew S. pneumoniae, were positive in the EIA. A total of 14 subsequent
culture-negative samples gave clear signals in the EIA up to day 15 after the onset of antibiotic treatment. For 11 CSF specimens, culture,
microscopy, and latex agglutination were negative while the EIA
detected pneumococcal antigens. The EIA did not react either with CSF
of patients with meningitis caused by bacteria other than S. pneumoniae or by viral pathogens. In conclusion, this EIA can be
a valuable tool for the diagnosis of S. pneumoniae
meningitis from CSF samples in cases in which prior antimicrobial
therapy minimizes the usefulness of culture or other antigen detection
tests.
