what does the oxidase test tell you about the physiology of the tested microorganisms?

Answer 1

The oxidase test is "performed to presumptively identify Neisseria species and to initially characterize gram negative bacilli, the oxidase test indicates the presence of the enzyme cytochrome oxidase."

Answer 2

in addition to testing for neisseria species, it can also be used to identify gram negative rods. Pseudomonas species are oxidase positive, while E. coli is oxidase negative. while identifying bacteria, you go through a series of tests based on previous test results which give yes or no answers. for example: the gram stain comes first. if you have a gram negative rod (E. coli) or gram negative diplococci (Neisseria species), the next step would be the oxidase test, etc, etc.
