Which one of the following bacteria ois oxidase positive?
High-Yield Explanation
Oxidase test: The test is used to identifying bacteria containing cytochrome oxidase. I t is useful in differentiating the oxidase negative Enterobacteriaceae from the oxidase positive Pseudomonas organisms and the oxidase positive group of vibrios and related bacterias (Aeromonas, Plesiomonas). Neisseria organisms also test positive. the presence of cytochrome oxidase can is detected through the use of an oxidase disc which acts as an electron donor to cytochrome oxidase. if the test bacterium oxidizes the disc, the disk turns pin indicating a positive test. If there is no change in color the test is negative for the bacterium REF:Ananthanarayan & Panicker's Textbook of Microbiology 8th Edition pg no: 675
