Abstract: The invention relates to a mass spectrometric method to determine microbial resistances to antibiotics. The decrease or modification of specific nutrient components by microbes, and thus the metabolism of the microbes, is determined mass spectrometrically in culture media containing antibiotics. Hence it is not the microbes which are introduced into the mass spectrometric analysis, but the culture medium. The special nutrient components which are subject to the mass spectrometric observation are indicators for the metabolism exhibited by the microbes in the culture in the presence of antibiotics, and are thus indicators for their susceptibility or resistance.
