Composition per liter:

Proprietary

Source: This medium is available from Biosynth In

ternational, Inc.

Use: To differentiate Listeria monocytogenes and L.

ivanovii from other Listeria spp. The supplements

render the medium selective. Differential activity for

all Listeria species is based upon a chromogenic sub

strate included in the medium. This is a complete test

system with a fluorogenic selective enrichment broth

and a chromogenic plating medium both detecting

the virulence factor Phosphatidylinositol specific

Phospholipase C (PI-PLC). The medium contains a

substrate for phosphotidylinositol-specific phospho

lipase 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 sub

strate with the additional production of a white pre

cipitate surrounding the target colonies.
