Bacterial Identification by Mass Spectrometry


Mass spectrometry (MS) is a mature analytic technology in the research community that has only recently begun to make significant inroads into the clinical laboratory. Matrix-assisted laser desorption/ ionization time-of-flight mass spectrometry (MALDITOF MS) is a relatively recent addition to the MS arsenal and shows great promise for the clinical laboratory. This webinar will focus on the use of MALDI-TOF and other MS techniques in the identification of microorganisms.

Originally presented on November 28, 2012, in Salt Lake City, Utah.

Dr. Fisher is the medical director of the Bacteriology, Antimicrobials, Parasitology, and Infectious Disease Rapid Testing laboratories at ARUP and an assistant professor of pathology at the University of Utah School of Medicine. Dr. Fisher obtained a PhD in microbiology and molecular genetics from Emory University and a master of science in microbiology from Idaho State University. He subsequently completed fellowships in microbial pathogenesis at the Rocky Mountain Laboratories (NIH) and in medical microbiology at the University of Utah. He is boardcertified in medical microbiology, and his research interests include microbial pathogenesis and transmission of vector borne pathogens.


After this presentation, participants will be able to:

  • Discuss relevant principles of mass spectrometry.
  • Review advantages and disadvantages of available platforms.
  • Discuss the use of mass spectrometry in the clinical microbiology laboratory.
