Brand:  Thermo Scientific™ CM0877B

Product Code. 10056352

Description

Detect and isolate Listeria monocytogenes from food samples with Thermo Scientific™ Oxoid™ PALCAM Agar Base (Dehydrated). The PALCAM Agar Base is highly selective and contains double indicator system that allows easy differentiation of Listeria monocytogenes, based upon aesculin fermentation, lack of mannitol fermentation and resultant pH change.

Listeria monocytogenes is the most common pathogenic Listeria spp. and has been shown to be pathogenic to both humans and animals. PALCAM Medium is based on the formulation described by Van Netten et al.¹ and is recommended for the isolation of Listeria monocytogenes from foods.

• Selective: the addition of lithium chloride, ceftazidime, polymyxin B and acriflavine hydrochloride make the medium highly selective for Listeria monocytogenes.
• Easy-to-read: monocytogenes forms brown/black colonies with a black halo while mannitol positive accompanying flora, such as staphylococci and enterococci, grow as yellow colonies.

PALCAM Medium allows easy differential diagnosis of L. monocytogenes by utilizing the double indicator system.

1. Aesculin and ferrous iron
2. Mannitol and phenol red

Listeria monocytogenes hydrolyses aesculin resulting in the formation of a black halo around colonies. L. monocytogenes does not ferment mannitol so can be easily differentiated from contaminants, such as enterococci and staphylococci, which ferment mannitol producing a change from red to yellow in the pH indicator phenol red.
