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 aeruginosaforms fluorescent green colonies while the growth ofKlebsiella, ProteusandProvidenciais strongly suppressed.
• Enhanced pigment production aids identification
• Conforms to U.S. Pharmacopeia^3and European Pharmacopoeia^1standards for Microbial Limit Tests.
• The formulation is in line with the A.O.A.C. guidelines^4for isolation of Pseudomonas aeruginosa from cosmetics and in A.O.A.C. method^5for 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.Not all products are available for sale in all territories.
