Thermo Scientific™ Oxichrome Reagent

Description

• Rapidly detect the enzyme cytochrome oxidase in microorganisms using Thermo Scientific™ Remel™ Oxichrome Reagent
• The oxidase test was originally developed to identify Neisseria spp., but later was used to separate pseudomonads from oxidase-negative enteric Gram-negative bacilli (Enterobacteriaceae) 1,2
• Most Gram-positive bacteria are oxidase-negative, pseudomonads are oxidase-positive, and other non-enteric, Gram-negative bacilli, are variable Pseudomonads, bacteria of the family Pseudomonadaceae are a large and varied group comprising four major genera and several hundred species
• Most species of the family are found in soil or water; some cause diseases in plants, and a few cause serious diseases in humans and other mammals
• Pseudomonas aeruginosa , very common and widespread, is an opportunistic pathogen for man that causes antibiotic-resistive infections in persons of weakened resistance
• The oxidase reaction is attributed to the presence of a cytochrome oxidase system in the respiratory chain of certain bacteria, which utilizes molecular oxygen as a terminal electron acceptor 3,4
• Oxidase-positive bacteria produce oxidase enzymes which, in the presence of atmospheric oxygen, cytochrome c, and an oxidase reagent (Oxichrome Reagent), oxidize the reagent to form a blue-purple colored compound, Wurster’s blue
• Ready-to-use – Liquid reagent Easy to interpret – Blue to purple color indicates a positive test Easy-to-store – Storage at room temperature Rapid results – Can be interpreted within 30 seconds Oxichrome reagent contains N,N,N,N-tetramethyl-ρ-phenylenediamine supplied in 15 mL bottles
