Background: Bacterial meningitis is a neurological emergency. Early diagnosis and rapid initiation of antimicrobial therapy are vital. Methods: Matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF MS) is increasingly used as a rapid and accurate microbial diagnostic method for species identification of pathogens. Although this technology requires a growth step to obtain bacterial colonies for the acquisition of substantial spectra in most cases, it can also be used to analyze clinical specimens such as urine and cerebrospinal fluid for direct bacterial identification. There are very few reports describing the use of MALDI-TOF MS for the direct detection of microorganisms causing bacterial meningitis. Results: We describe a case of bacterial meningitis caused by Klebsiella pneumoniae in which MALDI-TOF MS provided a rapid bacteriological diagnosis, thus enabling early and appropriate treatment. Conclusions: Identification of microbes based on MALDI-TOF MS is now an important technology in clinical microbiology laboratories that are required to provide a rapid diagnosis of bacterial meningitis.
