Cetrimide agar

From Wikipedia, the free encyclopedia

Cetrimide agar is a type of agar used for the selective isolation of the gram-negative bacterium, Pseudomonas aeruginosa.[1] As the name suggests, it contains cetrimide, which is the selective agent against alternate microbial flora.[2] Cetrimide also enhances 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.[1]
