Mass spectrometry: Pneumococcal meningitis verified and Brucella species identified in less than half an hour

Abstract

Matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) is currently being introduced for the rapid and accurate identification of bacteria. We describe 2 MALDI-TOF MS identification cases - 1 directly on spinal fluid and 1 on grown bacteria. Rapidly obtained results had great value for the continued treatment and for the elucidation of exposure.
