Cetrimide agar is a type of agar used for the selective isolation of the gram-negative bacteria, Pseudomonas aeruginosa. [1] As the name suggests, it contains cetrimide, which is the selective agent against alternate microbial flora. [2] Cetrimide also inhances the production of Pseudomonas pigments such as pyocyanin and fluorescein, which show a characteristic blue-green and yellow-green colour, respectively. [3] [4]
Cetrimide agar is widely used in the examination of cosmetics, pharmaceuticals and clinical specimens to test for the presence of Pseudomonas aeruginosa. [5]
