Methods for Storing Oxidase Test Reagents [PDF]
Applied Microbiology, 1969 Oxidase test reagents are notoriously unstable, but they can be held ready for use if frozen or if reagent-impregnated filter paper is kept dry.

Fatal
Annals of Clinical Microbiology and Antimicrobials, 2009 Background Chromobacterium violaceum is a Gram negative facultative anaerobic bacillus, found in soil and stagnant water, that usually has a violet pigmented appearance on agar culture. It is rarely described as a human pathogen, mostly from tropical and

Rapid, modified oxidase test for oxidase-variable bacterial isolates
Journal of Clinical Microbiology, 1982 A modified oxidase reagent, 1% tetramethyl-p-phenylenediamine in dimethyl sulfoxide, proved superior to the routinely used 1% aqueous tetramethyl-p-phenylenediamine dihydrochloride in detecting weakly oxidase-positive gram-negative bacteria after 24 h of growth on agar media (40 of 40 positive versus 22 of 40 positive).

The oxidase test in yeasts of medical importance [PDF]
Journal of Medical Microbiology, 1987 The results of an oxidase test were positive with species of Cryptococcus and eight species of Candida, but negative with Candida krusei and species of Saccharomyces and Torulopsis, grown on Columbia Agar base and similar media, including Brain Heart Infusion Agar and Mueller Hinton Agar.

Use of a quantitative oxidase test for characterizing oxidative metabolism in bacteria [PDF]
Applied and Environmental Microbiology, 1976 It was possible to quantitate the terminal oxidase(s) reaction using bacterial resting-cell suspensions and demonstrate the usefulness of this reaction for taxonomic purposes. Resting-cell suspensions of physiologically diverse bacteria were examined for their capabilities of oxidizing N,N,N',N'-tetramethyl-p-phenylenediamine (TMPD) using a manometric ...

Survey of Oxidase-Positive and -Negative Bacteria Using a Quantitative Kovacs Oxidase Test [PDF]
International Journal of Systematic Bacteriology, 1976 A manometric assay system employing ascorbate and N,N,N',N'-tetra-methyl-p-phenylenediamine (TMPD) was used to quantitate terminal oxidase activity in bacterial non-proliferating whole cells. A wide variety of physiologically diverse bacteria, all of which were grown heterotrophically, was tested by this assay.

A Simple Litmus Test for Aldehyde Oxidase Metabolism of Heteroarenes [PDF]
Journal of Medicinal Chemistry, 2014 The bioavailability of aromatic azaheterocyclic drugs can be affected by the activity of aldehyde oxidase (AO). Susceptibility to AO metabolism is difficult to predict computationally and can be complicated in vivo by differences between species. Here we report the use of bis(((difluoromethyl)sulfinyl)oxy)zinc (DFMS) as a source of CF2H radical for a ...

Serum diamine oxidase (DAO) activity as a diagnostic test for histamine intolerance [PDF]
Clinical and Translational Allergy, 2011 Background Histamine intolerance (HIT) is characterized by an imbalance between histamine intake and the capacity for histamine degradation. The main enzyme for metabolizing ingested histamine is diamine oxidase (DAO). Determining DAO activity in serum may be useful in diagnosing HIT.

APPLICATION OF THE OXIDASE TEST TO REFRIGERATED DELICATESSEN FOODS [PDF]
Journal of Milk and Food Technology, 1969 A total bacterial count, oxidase count, coliform, and yeast and mold count was made on each of 135 samples of delicatessen foods collected at retail outlets and food processing plants. Analysis of the data obtained, primarily through correlation of the total count, oxidase and coliform counts, allowed for an assessment of possible sources of bacterial ...
