Cetrimide Agar is intended primarily for use in the isolation of Pseudomonas aeruginosa from pharmaceutical products and is recommended by the United States Pharmacopoeia for this purpose.
The medium is made selective by the addition of cetrimide to inhibit the growth of most other organisms while allowing Pseudomonas aeruginosa/ and other Pseudomonas spp. to develop a classical colonial appearance, producing green pigmentation and fluoresce when examined under ultra violet light.
