Thermo Scientific™ PALCAM Agar Base (Dehydrated)

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
• Aesculin and ferrous iron 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
