This book highlights the triumph of MALDI-TOF mass spectrometry over the past decade and provides insight into new and expanding technologies through a comprehensive range of short chapters that enable the reader to gauge their current status and how they may progress over the next decade.  This book serves as a platform to consolidate current strengths of the technology and highlight new frontiers in tandem MS/MS that are likely to eventually supersede MALDI-TOF MS. Chapters discuss:Challenges of Identifying Mycobacterium to the Species level Identification of and Other Clinically Relevant AnaerobesIdentification of Species in Mixed Microbial PopulationsDetection of Resistance MechanismsProteomics as a biomarker discovery and validation platformDetermination of Antimicrobial Resistance using Tandem Mass Spectrometry
