Oxidase Discs
Oxidase discs are ascorbic acid, a-naphthol, N, N-dimethyl-pphenylenediamine, and oxalate impregnated sterile filter paper discs. These discs eliminate the need for fresh reagent preparation on a daily basis.
Oxidase discs are impregnated with a reagent, typically tetramethyl-p-phenylenediamine dihydrochloride, which acts as an electron donor.
These discs help in differentiating oxidase-positive bacteria (e.g., Pseudomonas, Neisseria, and Vibrio) from oxidase-negative bacteria (e.g., Enterobacteriaceae family like Escherichia coli and Salmonella). It is also utilized in clinical labs to quickly identify potential pathogens.
