Substrate for identifying pathogenic Listeria, is cleaved by an esterase, other than phosphatidylinositol-specific phospholipase C, that is specific for L. monocytogenes

摘要

Substrate (S), for direct identification of pathogenic Listeria species, which is cleaved by an esterase activity, other than phosphatidylinositol-specific phospholipase C (PI-PLC) activity, that is specific for Listeria monocytogenes, is new. Independent claims are also included for the following: (1) reaction medium (M) for direct identification of L. monocytogenes containing at least one (S); (2) identifying L. monocytogenes by inoculating (M) with test sample; and (3) use of a substrate containing a target part, i.e. (S), and an inhibitory part that inhibits L. monocytogenes specifically when released.
