Oxidase Strips are a rapid diagnostic test for the detection of the cytochrome oxidase activity of microorganisms. Oxidase Test is an important differential procedure which is performed on all gram-negative bacteria that are to be identified. In presence of the enzyme cytochrome oxidase (produced by gram-negative bacteria) the N,N-dimethyl-phenylenediamine, and alpha-naphthol impregnated on the strips react to indophenol blue which is visible by a color change.
Application:
Oxidase Strips are used for detection of oxidase production by microorganisms like Neisseria, Alcaligenes, Aeromonas, Vibrio′s, Campylobacter and Pseudomonas.
