Affirm any suspect colonial progress on one or more on the media as Pseudomonas aeruginosa via the oxidase test. On the colonial development position or transfer colonies to strips or disks of filter paper that Earlier has become impregnated with N,N-dimethyl-p-phenylenediamine dihydrochloride: if there is no improvement of a pink shade, switching to purple, the specimen meets the necessities on the test to the absence of Pseudomonas aeruginosa.
