Method for detecting delta haemolysin of Staphylococcus aureus by mass spectrometry directly using a bacterial population

摘要

The present invention relates to a method for studying a sample containing a bacterial population of Staphylococcus aureus with a specific mass spectrometry technique allowing specific detection on the obtained mass spectrum of the presence or of the absence of a peak at an m/z value of 3005±5 Th Thomson or at 3035±5 Th Thomson, and accordingly, to the issuance of a decision conditioned by this result.
