Meningitis is a serious communicable disease with high morbidity and mortality rates. It is an endemic disease in Egypt caused mainly by<jats:italic>Streptococcus pneumoniae<\/jats:italic>,<jats:italic>Neisseria meningitidis<\/jats:italic>, and<jats:italic>Haemophilus influenzae<\/jats:italic>. In some settings, bacterial meningitis is documented depending mainly on positive cerebrospinal fluid (CSF) culture results or CSF positive latex agglutination test, missing the important role of prior antimicrobial intake which can yield negative culture and latex agglutination test results. This study aimed to utilize molecular technology in order to diagnose bacterial meningitis in culture-negative CSF samples.<jats:italic>Materials and Methods<\/jats:italic>. Forty culture-negative CSF samples from suspected cases of bacterial meningitis were examined by real-time polymerase chain reaction (real-time PCR) for the presence of<jats:italic>lytA<\/jats:italic>,<jats:italic>bexA<\/jats:italic>, and<jats:italic>ctrA<\/jats:italic>genes specific for<jats:italic>Streptococcus pneumoniae<\/jats:italic>,<jats:italic>Haemophilus influenzae<\/jats:italic>, and<jats:italic>Neisseria meningitidis<\/jats:italic>, respectively.<jats:italic>Results<\/jats:italic>. Positive real-time PCR results for<jats:italic>Streptococcus pneumoniae<\/jats:italic>were detected in 36 (90%) of culture-negative CSF samples while no positive results for<jats:italic>Haemophilus influenzae<\/jats:italic>or<jats:italic>Neisseria meningitidis<\/jats:italic>were detected. Four (10%) samples were negative by real-time PCR for all tested organisms.<jats:italic>Conclusion<\/jats:italic>. The use of molecular techniques as real-time PCR can provide a valuable addition to the proportion of diagnosed cases of bacterial meningitis especially in settings with high rates of culture-negative
