Abstract

The invention relates to a method for identifying a microorganism by mass spectrometry including: acquiring at least one mass spectrum of said microorganism; for each mass spectrum acquired: detecting peaks of the spectrum in a predetermined range of masses and generating a list of peaks containing no more than one peak in each interval of a predetermined subdivision of the range of mass to charge ratios the width of the intervals of the subdivision logarithmically increasing with the mass to charge ratio; and analysing the obtained list(s) of peaks in accordance with a knowledge base of previously identified microorganisms and/or types of microorganisms.
