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