General description

Oxidase Reagent A, according to Gaby-Hadley, is a commonly used laboratory reagent employed in microbiology for the detection of bacteria that produce cytochrome c oxidase. The reagent is designed to identify the presence of this enzyme, which plays a critical role in the electron transport chain and is indicative of the respiratory metabolism in bacteria.The Gaby-Hadley reagent A contains alpha-naphthol as the active component in the reagent. When an organism produces cytochrome c oxidase, the reagent undergoes a color change reaction, turning from colorless to blue or purple. This color change is a positive result, indicating the presence of cytochrome c oxidase activity in the tested organism.

Application

Oxidase Reagent A, according to Gaby-Hadley, is a commonly used laboratory technique in industrial microbiology to differentiate between bacterial strains based on their ability to produce cytochrome c oxidase. The Gaby-Hadley A reagent provides a simple and efficient way to identify oxidase-positive bacteria, such as Pseudomonas, Vibrio, and some Neisseria species, while producing negative results for organisms that lack cytochrome c oxidase activity. in the food, beverage, and pharmaceutical industries.

Vibrio Detection

Vibrios are motile, curved or comma-shaped bacilli and have a single polar flagella with sheet proteins. They are often found in open water, freshwater and saltwater.

On the Trail of Campylobacter

On the Trail of Campylobacter - The Campylobacter is one of the leading causes of human gastroenteritis. Common Campylobacter species C. jejuni, C. coli, and C. lari are responsible for most cases of campylobacteriosis. However, other species, like C. fetus, which causes spontaneous abortions, have also been associated with human illness. Campylobacter are Gram-negative, spiral-shaped, microaerophilic and motile bacteria with uni- or bi-polar fl agella

Media for Staphylococcus Aureus Detection

Chromogenic media enable the selective detection of S. aureus, which produce bluish-green colonies that are clearly differentiated from other species.

Identification of Microorganisms Based on Color

For microbiologists the most fundamental stain was developed in 1884 by the Danish bacteriologist Hans Christian Gram.

Listeria: a Survivor

In recent years it has been recognized that Listeria is an important public health problem. The disease affects primarily people of advanced age, pregnant women, newborns, and adults with weakened immune systems.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
