Is the cytochrome oxidase test indirect

The oxidase test is used to determine if an organism possesses the cytochrome c oxidase enzyme. The test is used as an aid for the differentiation of Neisseria, Moraxella, Campylobacter and Pasteurella species (oxidase positive). It is also used to differentiate pseudomonads from related species. Zobacz więcej Strains may be either oxidase-positive (OX+) or oxidase-negative (OX-). OX+ OX+ normally means the bacterium contains cytochrome c oxidase (also known as … Zobacz więcej The test uses disks impregnated with a reagent such as N,N,N′,N′-tetramethyl-p-phenylenediamine, TMPD (or N,N-dimethyl-p-phenylenediamine, DMPD, which is also a redox indicator). The reagent is a dark-blue to maroon color when oxidized, … Zobacz więcej • Oxidase test video • Oxidase Test Procedure Zobacz więcej WitrynaBactident ™ Oxidase test strips are designed to detect cytochrome oxidase positive microorganisms in a test sample or grown culture. Cytochrome oxidase is an enzyme found in specific microbes which will catalyze the substrate cytochrome c indicated by a color change of blue to blue violet.
