Direct MALDI-TOF MS Testing from Positive Blood Cultures for Rapid Identification of Bloodstream Infection-Causing Anaerobic Bacteria.

Direct use of matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) on positive blood culture (PBC) bottles may accelerate the identification of bloodstream infection (BSI) causing organisms (1), particularly anaerobic bacteria for which BSI-associated mortality rates are high (2).….
