Biosynth Chromogenic Medium
for Listeria monocytogenes
(BCM for Listeria monocytogenes)
(BAM M17a)
Composition per liter:
Proprietary
Source:  This medium is available from Biosynth International, Inc.
Use:  To differentiate Listeria monocytogenes and L. ivanovii from
other Listeria spp. Supplements render the medium selective. Differen-
tial activity for all Listeria species is based upon a chromogenic sub-
strate included in the medium. This is a complete test system with a flu-
orogenic selective enrichment broth and a chromogenic plating
medium both detecting the virulence factor phosphatidylinositol spe-
cific phospholipase C (PI-PLC). The medium contains a substrate for
phosphatidylinositol-specific phospholipase C (PlcA) enzymes. The
selective enrichment broth is fluorogenic. The plating medium for
rapid detection and enumeration of pathogenic Listeria combines
cleavage of the chromogenic PI-PLC substrate with the additional pro-
duction of a white precipitate surrounding the target colonies.
