We used broad-range bacterial PCR combined with DNA sequencing to
examine prospectively cerebrospinal fluid (CSF) samples from patients
with suspected meningitis. Fifty-six CSF samples from 46 patients were
studied during the year 1995. Genes coding for bacterial 16S and/or 23S
rRNA genes could be amplified from the CSF samples from five patients
with a clinical picture consistent with acute bacterial meningitis. For
these patients, the sequenced PCR product shared 98.3 to 100% homology
with the Neisseria meningitidis sequence. For one patient,
the diagnosis was initially made by PCR alone. Of the remaining 51 CSF
samples, for 50 (98.0%) samples the negative PCR findings were in
accordance with the negative findings by bacterial culture and Gram
staining, as well as with the eventual clinical diagnosis for the
patient. However, the PCR test failed to detect the bacterial rRNA gene
in one CSF sample, the culture of which yielded Listeria
monocytogenes. These results invite new research efforts to be
focused on the application of PCR with broad-range bacterial primers to
improve the etiologic diagnosis of bacterial meningitis. In a clinical
setting, Gram staining and bacterial culture still remain the
cornerstones of diagnosis.
