Abstract: Microorganisms are identified as present in a complex sample or mixed culture by acquiring a mass spectrum of the sample and comparing it to combination spectra, each of which is formed by combining at least two reference mass spectra of known microorganisms. Microorganisms corresponding to the reference spectra used to form the combination spectrum are identified as present in the sample if that combination spectrum exhibits a better match with the sample mass spectrum than any one of reference mass spectra used to form that combination spectrum. It is also possible to identify microorganisms by forming a difference spectrum by subtracting a reference mass spectrum from the sample mass spectrum and comparing the difference spectrum to the reference mass spectra.

Abstract: The invention mainly relates to the mass spectrometric identification of pathogens in blood cultures from bloodstream infections (septicemia). The invention provides a method with which microbial pathogens can be separated in purified form from blood after a relatively brief cultivation in a blood culture flask, without any interfering human proteins or any residual fractions of blood particles such as erythrocytes and leukocytes, and can be directly identified by mass spectrometric measurement of their protein profiles. The method is based on the use of relatively strong tensides to destroy the blood particles by dissolving the weak cell membranes and most of the internal structures of the blood particles; in spite of the fact that tensides are regarded as strong ionization inhibitors in MALDI and other ionization processes required for mass spectrometric measurements.
