Bacterial meningitis is a life-threatening condition that requires quick and definitive diagnosis. Bacterial cultures from cerebrospinal fluid (CSF) return with a negative result as treatment with antimicrobials are sometimes started before sampling of CSF can be obtained which makes isolating the causative bacteria challenging. The value of Broad Range 16S Ribosomal RNA Gene Polymerase Chain Reaction / Sequencing of CSF (Br-PCR) can address this problem by amplifying and identifying any bacterial DNA present in a clinical sample. A 65-year-old female presented with rapid onset of high fevers, headache, chills and right hip pain. She had blood cultures drawn, unremarkable CSF analysis in the emergency department, and was discharged home. Ten hours later, she developed vomiting and altered mental status, returned to hospital and started on antimicrobials for gram negative bacteremia and emergently intubated with repeat lumbar puncture showed evidence of bacterial meningitis with pleocytosis and elevated opening pressures. Empiric antimicrobial therapy was started. All subsequent CSF microbiological stains, cultures, and molecular analyses were negative. The blood cultures grew Haemophilus influenzae and H. influenzae meningitis was presumed to be the cause. Therefore, Br-PCR on CSF was sent which detected Haemophilus species DNA. She received a 3-week course of ceftriaxone. After rehabilitation, she returned home without any significant neurological deficits. No relapse of meningitis at 4 months was noted. The application for Br-PCR in the setting of suspected bacterial meningitis with negative stains and cultures could improve a diagnostic algorithm for bacterial meningitis.
