Novel enzymatic substrates for the detection of pseudomonas aeruginosa, compositions containing them and method of detection of this species

摘要

The invention concerns an enzymatic substrate consisting of a target portion and a marker portion, the target portion being separated from the marker portion by hydrolysing the substrate, said target portion characterising the desired enzymatic activity. The invention also concerns a composition containing at least such a substrate and a method for detecting the iPseudomonas aeruginosa/i bacterial species. The target portion of the substrate enables to reveal a beta -alanine aminopeptidase enzymatic activity and the marker portion is a molecule revealing the hydrolysis reaction. The invention is particularly useful in the field of diagnosis.
