Oxidase Discs (50 discs / vl)

Details

Oxidase Discs are used for detection of oxidase production by microorganisms like Neisseria, Alcaligenes, Aeromonas, Vibrio`s, Campylobacter and Pseudomonas, which give positive reactions and for excluding Enterobacteriaceae, which give negative reactions. Oxidase discs are sterile filter paper discs impregnated with N, N-dimethyl-p-phenylenediamine oxalate, ascorbic acid and a-naphthol. These discs overcome the neccessity of daily preparation of fresh reagent. Pseudomonas aeruginosa ATCC 27853 positive : deep purplish blue colouration of disc ; Staphylococcus aureus ATCC 25923 negative : no colour change.
