Method and device for the detection of carbapenemases and carbapenemase producers

The invention refers to a method and a device for the phenotypic detection of carbapenemases and carbapenemase producers by adding a substrate of general formula A-(L)-M.sub.1-(X)—Z, where M.sub.1 is a carbapenem backbone, A or Z is a quencher, the other one of the two, Z or A, is a fluorophore, L is an optional linker, X is an optional leaving group for linking Z to the carbapenem backbone, and Z is an optional leaving group, to a sample suspected of containing such carbapenemase producers and/or carbapenenmases. The invention further refers to a method for the phenotypic detection of resistant bacteria, in particular 3MRGN or 4MRGN, by releasing the enzymes of a bacterial culture into a lysate during lysis and then subjecting the lysate, as the sample to be analyzed, to an aforementioned method in order to phenotypically detect the presence of resistance-conferring carbapenemases.

6,7-trans cephalosporin-based probes for detecting bacteria expressing a metallo-beta-lactamase

The present invention discloses a probe useful for the selective detection of metallo-beta-lactamases, in particular carbapenemases, thereby distinguishing those species of bacteria that are carbapenem-resistant from bacterial strains that are sensitive. Cephalospori based probes that have the 6,7 R,R configuration are susceptible to cleavage by beta-lactamases but cannot distinguish between cleavage by metallo-beta-lactamases and other beta-lactamases. By modifying a side group of the cephalosporin, selectivity can be introduced allowing the probes to distinguish between various types of metallo-beta-lactamases.
