Thermo Scientific™ Lysine Iron Agar (Dehydrated)

Description

• Detect salmonellae including Salmonella arizonae with the diagnostic Thermo Scientific™ Oxoid™ Lysine Iron Agar (Dehydrated)
• This differential medium detects salmonellae (including lactose fermenting Salmonella arizonae) by lysine decarboxylase activity and H 2 S production
• Salmonella infection (salmonellosis) is a common bacterial disease that affects the intestinal tract
• Salmonella bacteria typically live in animal and human intestines and are shed through faeces
• Humans become infected most frequently through contaminated water or food
• Lysine Iron Agar is a sensitive medium for the detection of lactose fermenting and lactose non-fermenting Salmonella species
• Many strains of this group ferment lactose so quickly that the expected positive reaction for hydrogen sulphide are suppressed on some media like Triple Sugar Iron Slants
• So there is a possibility that these organisms found in food poisoning outbreaks could be overlooked
• The only recognised groups of Enterobacteriaceae which regularly decarboxylate lysine rapidly and which produce large amounts of hydrogen sulphide, are the salmonellae 1,2 .Lysine Iron Agar is a sensitive medium for the detection of lactose-fermenting and non-lactose-fermenting salmonellae
• Typical reactions of organisms in Lysine Iron Agar: Cultures Slant Butt H 2 S Salmonella Alkaline Alkaline + Proteus Red Acid - Providencia Red Acid - Citrobacter Alkaline Acid + Escherichia Alkaline Acid or neutral - Shigella Alkaline Acid - Klebsiella Alkaline Alkaline - Not all products are available for sale in all territories
