Is coryne bacterium is oxidase positive?
no.coryne bacterium is oxidase negative.
Why is an oxidase test performed on a culture before using API 20E and Enterotube II to identify the culture?
API 20E and Enterotube II are for the identification of oxidase- negative bacteria. If the oxidase test is positive, these two methods of identification would be useless.
Can an aerobic organsm be oxidase negative?
No, the aerobic organism cannot be oxidase negative. This is because the aerobic organisms use oxygen as the electron acceptor. The aerobic organism are therefore oxidase positive.
Why is it advisable to include a known oxidase-positive control in any test of an unknown organism?
It's advisable so that the oxidase test determines whether or not an organism has cytochrome oxidase in its electron transport chain.
Which bacteria is NLF oxidase negative motile citrate and urease positive and TSI alkali nochange?
S.maltophila
The oxidase test is used to differentiate among which groups of bacteria?
Differentitate among members of the genera Neisseria and Pseudomonas which are oxidase positive and Enterobacteriaceae which are oxidase negative.
Is coryne bacterium is oxidase positive?
no.coryne bacterium is oxidase negative.
Is Alcaligenes faecalis oxidase positive?
yes and no, sometimes it comes out positive and sometimes it comes out negitive
Why are strict aerobic oxidase-positive?
Strict aerobes must be oxidase positive because oxidase is an enzyme. It is critical to cellular respiration, specifically the final reduction of oxygen in the electron transport chain.
Why are strict aerobes oxidase positive?
Strict aerobes must be oxidase positive because oxidase is an enzyme. It is critical to cellular respiration, specifically the final reduction of oxygen in the electron transport chain.
How can you easily distinguish enterics and pseudomonads?
Enterics are oxidase negative while pseudomonads are oxidase positive.
Does E. coli test positive for oxidase?
no

API 20E and Enterotube II are for the identification of oxidase- negative bacteria. If the oxidase test is positive, these two methods of identification would be useless.
Are all aerobic bacteria oxidase positive?
yes, all aerobic cells are oxidase positive. The oxidase test is testing for the presence of cytochrome oxidase [by reducing it with an artificial substrate which turns purple when oxidised]. In aerobic cells cytochrome oxidase's normal role is in the electron transport chain, passing electrons from cytochrome c to oxygen. hence if the cell is aerobic then oxygen is terminal electron acceptor in the cells ETC and thus it will give a positive result in the oxidase test.
Is Klebsiella pneumoniae oxidase positive?
No, but Pseudomonas aeruginosa is.
Which bacilli are gram positive oxidase negative and catalase positive?
Streptobacillus is a gram negative, oxidase negative, catalase negative, non motile organism, and 0.3-0.7 µm by 1-5 µm in lengthEscherichia coliMost of the Enterobacteriaceae are Catalase Positive. E. coli is Catalase Positive and Oxidase Negative. Do not report the previous as an answer. For gram negative, catalase negative and oxidase negative rods, it is likely that you have bacteria of the Bacteroides genus.
What is Oxidase test results for bacillus subtilis?
It is NEGATIVE
