  • Method for determining the reaction of a microorganism to its exposure to a chemical compound
    Patent number: 10704075
    Abstract: The invention concerns a method for determining the reaction of at least one bacterium of interest to its exposure to an antibiotic implementing a Raman spectroscopy analysis comprising the following steps: Having a biological sample that could contain said bacteria of interest, Preparing at least two fractions of said sample each comprising one or more living bacteria of interest, Capturing, in each fraction, at least one living bacterium of interest by using a binding partner, Exposing at least one of the fractions to at least one concentration of at least one given antibiotic, the other of the fractions being the control fraction, Submitting the bacterium/bacteria of interest contained in the fractions to an incident light and analyzing the resultant light obtained by Raman diffusion by the bacterium/bacteria of interest by Raman spectroscopy in order to obtain as many Raman spectra as bacteria, Treating said spectra in order to obtain a signature of the reaction of the or each bacterium/bacteria of int
