CETRIMIDE AGAR BASE (VEG.)

This medium is prepared by replacing Gelatin peptone with Veg Peptone No.2. Cetrimide Veg Agar Base is the modification of Cetrimide Agar Base which is based on the formula described by King et al. It is used as a selective medium for the isolation of Pseudomonas aeruginosa from pus, sputum and drains etc. Also used for determining the ability of an organism to produce fluorescein and pyocyanin.
For the isolation of Pseudomonas aeruginosa, plates of Cetrimide Veg Agar Base should be inoculated from non-selective medium such as Brain Heart Infusion Broth Veg or Soyabean Veg medium. If the count is high the test sample can be directly inoculated onto this medium. Pseudomonas aeruginosa colonies may appear blue, blue-green or nonpigmented.
