The oxidase test is used to determine whether 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. [1]
Pseudomonas species also typically give a positive result to the oxidase test, the absence of gas formation from glucose, glucose is oxidised in oxidation/fermentation test using Hugh and Leifson O/F test, beta hemolytic (on blood agar), indole negative, methyl red negative, Voges–Proskauer test negative, and citrate positive.

The organism is considered opportunistic insofar as serious infection often occurs during existing diseases ... catalase, and oxidase positive. It is found in soil, ...
Photobacterium is a genus of gram-negative, oxidase positive and catalase positive bacteria in the family Vibrionaceae. [1] Members of the genus are bioluminescent , that is they have the ability to emit light .
Pasteurella is a genus of Gram-negative, facultatively anaerobic bacteria. [1] [2] Pasteurella species are nonmotile and pleomorphic, and often exhibit bipolar staining ("safety pin" appearance). Most species are catalase- and oxidase-positive. [3]
Vibrio spp. are facultative anaerobes that test positive for oxidase and do not form spores. [4] [5] All members of the genus are motile. They are able to have polar or lateral flagellum with or without sheaths. [4] [6] Vibrio species typically possess two chromosomes, which is unusual for bacteria.
Moraxella is a genus of gram-negative bacteria in the family Moraxellaceae.It is named after the Swiss ophthalmologist Victor Morax.The organisms are short rods, coccobacilli, or as in the case of Moraxella catarrhalis, diplococci in morphology, with asaccharolytic, oxidase-positive, and catalase-positive properties.

Plesiomonas can be distinguished from Shigella in diarrheal stools by an oxidase test: Plesiomonas is oxidase positive and Shigella is oxidase negative. Plesiomonas is easily differentiated from Aeromonas sp. and other oxidase-positive organisms by standard biochemical tests. [11]
