Pseudomonas aeruginosa is a Gram-negative micro-organism which grows on selective media containing cetrimide and produces pyocyanin, a blue-green pigment. Due to the presence of cetrimide and nalidixic acid, the medium inhibits interfering Gram-positive flora and for some Gram-negative micro-organisms. The presence of magnesium chloride and potassium sulfate favors the production of pyocianin pigment by Pseudomonas aeruginosa. The interpretation of results according to ISO16266 is pretty complex: all colonies that produce blue/green pigment shall be confirmed as Pseudomonas aeruginosa - examining membranes under UV all non-pyocyanin producing colonies that fluoresce shall be evaluated as presumptive Pseudomonas aeruginosa and their identity confirmed using Acetamide Broth - all other reddish-brown colonies that do not fluoresce shall be evaluated as presumptive Pseudomonas aeruginosa and their identity confirmed using the Oxidase test, Acetamide Broth and King B agar. Medium shall be supplemented.
