Abstract:
1. A composition for detecting a target microorganism in a sample, comprising a growth-supporting medium for the specific enrichment of a target microorganism, wherein said growth-supporting medium contains antibiotics to suppress the growth of non-target microorganisms and a conditionally detectable marker that undergoes a color change when reacted upon by a viable microorganism in the sample, wherein the color change is produced by a biochemical reduction of the conditionally detectable marker, and a substrate for an aminopeptidase, wherein said aminopeptidase is substantially absent from the target microorganism, wherein said target microorganism is Campylobacter , wherein said substrate comprises a signal moiety, the signal moiety capable of providing a detectable signal when cleaved by non-target microorganisms in the sample, and wherein said conditionally detectable marker and said substrate for an aminopeptidase are not the same molecule.
