• Cetrimide Agar (USP, EP) is a modification of the original medium described by Brown and Lowbury 2 for the selective isolation and differentiation of Pseudomonas aeruginosa from a range of samples
• Cetrimide is a quaternary ammonium compound with bactericidal activity against a broad range of Gram-positive organisms and some Gram-negative organisms
• Pseudomonas aeruginosa forms fluorescent green colonies while the growth of Klebsiella, Proteus and Providencia is strongly suppressed
• Enhanced pigment production aids identification Conforms to U.S
• Pharmacopeia 3 and European Pharmacopoeia 1 standards for Microbial Limit Tests
• The formulation is in line with the A.O.A.C
• guidelines 4 for isolation of Pseudomonas aeruginosa from cosmetics and in A.O.A.C
• method 5 for testing disinfectants on hard surfaces
• Pseudomonas aeruginosa produces a number of water soluble iron chelators, including the yellow-green or yellow-brown fluorescent pyoverdin
• When pyoverdin combines with the blue water-soluble pyocyanin, the bright green colour characteristic of Pseudomonas aeruginosa is created
• The addition of magnesium chloride and potassium sulphate enhances the production of these chelators
