Claim Text:
1. A method for labeling specifically living bacteria of a given category of bacteria in a sample comprising bacteria, the method comprising the steps of: a) incubating said bacteria of said sample with at least one analog of a monosaccharide compound, said monosaccharide being an endogenous monosaccharide residue of glycans of the outer membrane of the given category of bacteria, the endogenous monosaccharide residue comprising an ulosonic acid or ulosonate salt residue, the analog of a monosaccharide compound being a modified monosaccharide substituted at a given position by a first reactive group capable of reacting with a second reactive group of a labeling molecule, b) contacting said bacteria with a labeling molecule comprising a second reactive group, for generating the reaction of said first reactive group of said analog residue incorporated within said glycans of the outer membrane of said living bacteria with said second reactive group of said labeling molecule.
