Media-dependent oxidase reaction in a strain of Aeromonas hydrophila. 1977

V A McGrath, and S B Overman, and T L Overman

A strain of Aeromonas hydrophila isolated from bile was oxidase positive only when grown on nonselective media. The isolate was oxidase negative when grown on gram-negative selective and/or differential media. It is proposed that oxidase tests on gram-negative rods be performed on colonies grown on nonselective media to assure valid results.

UI	MeSH Term	Description	Entries
D010088	Oxidoreductases	The class of all enzymes catalyzing oxidoreduction reactions. The substrate that is oxidized is regarded as a hydrogen donor. The systematic name is based on donor:acceptor oxidoreductase. The recommended name will be dehydrogenase, wherever this is possible; as an alternative, reductase can be used. Oxidase is only used in cases where O2 is the acceptor. (Enzyme Nomenclature, 1992, p9)	Dehydrogenases,Oxidases,Oxidoreductase,Reductases,Dehydrogenase,Oxidase,Reductase
D003470	Culture Media	Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN.	Media, Culture
D000333	Aeromonas	A genus of gram-negative, facultatively anaerobic, rod-shaped bacteria that occurs singly, in pairs, or in short chains. Its organisms are found in fresh water and sewage and are pathogenic to humans, frogs, and fish.
