OX+ normally means the bacterium contains cytochrome c oxidase (also known as Complex IV) and can therefore use oxygen for energy production by converting O 2 to H 2 O 2 or H 2 O with an electron transfer chain. The Pseudomonadaceae are typically OX+. [1] The Gram-negative diplococci Neisseria and Moraxella are oxidase-positive. [2]

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.

Furthermore, fundamental differences between these two species are again shown, as serological testing reveals N. flavescens' lack of cross-agglutination. [2] At the same time, biochemical testing distinguishes Neisseria flavescens from other gram-negative diplococci , with N. flavescens being DNase negative, weakly positive to Superoxol, and ...
Achromobacter xylosoxidans (formerly Alcaligenes xylosoxidans) is a Gram-negative, aerobic, oxidase and catalase-positive, motile bacterium with peritrichous flagella, from the genus Achromobacter. It is generally found in wet environments.
However, H. influenzae isolated from cerebrospinal fluid or blood or joint fluid would indicate invasive H. influenzae infection. Microscopic observation of a Gram stained specimen of H. influenzae will show Gram-negative coccobacillus. The cultured organism can be further characterized using catalase and oxidase tests, both of which should be ...
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.
Plesiomonas shigelloides is a species of bacteria [1] and the only member of its genus. It is a Gram-negative, rod-shaped bacterium which has been isolated from freshwater, freshwater fish, shellfish, cattle, goats, swine, cats, dogs, monkeys, vultures, snakes, toads and humans. [2] It is considered a fecal coliform.
