Description: A.R.I.A Medium with 5% Horse Blood and Neomycin
Quantity: 10/Pk.
Manufacturing Origin: United Kingdom
Unit Size: Each
Made from Thermo Scientific™ Oxoid™ dehydrated culture media, A.R.I.A contains 5% defibrinated horse blood and peptones, carefully selected to support the growth of anaerobic bacteria. Neomycin is present as a selective agent for obligate anaerobes. The following constituents have been added to the formulation to enhance performance:
• Yeast extract provides a vitamin source, and starch is present to absorb any toxic metabolites
• L-cysteine is present as a reducing agent and has shown to stimulate the growth of some anaerobes^1
• Glucose is the main carbohydrate, and sodium pyruvate is also added as an energy source for asaccharolytic cocci, such as Veillonella
• Haemin and Vitamin K are also included as growth factors required by many Bacteriodes species^2
• Neomycin is present as a selective agent for obligate anaerobes1. Shanson DC, Singh J.
