Thermo Scientific™ MLCB Agar (Dehydrated)

Description

• Selectively isolate salmonellae other than Salmonella Typhi and Salmonella Paratyphi A from and food samples with Thermo Scientific™ Oxoid™ MLCB Agar (Dehydrated)
• MLCB Agar is based on the formula of Inoue et al
• 1 for the selective isolation of salmonellae from feces and foods
• Visual detection of very small numbers of hydrogen sulphide-producing strains is easy because of the distinctive colonial appearance
• 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 feces
• Humans become infected most frequently through contaminated water or food
• Use MLCB Agar for selective isolation of other than Salmonella typhi and Salmonella paratyph i A from feces and food samples
• The medium may be inoculated directly with the specimen or from an enrichment culture
• Salmonellae grow as large purple-black colonies due to hydrogen sulphide production
• Mannitol is utilized by the organism and the resultant pH fall initiates lysine decarboxylation which controls further downward pH movement and promotes blackening
• MLCB Agar does not depend on lactose fermentation and is therefore recommended when investigating lactose-fermenting salmonellae ( Salmonella arizona )
• Atypical Salmonella strains that produce little or no hydrogen sulphide grow as mauve-grey colonies and may develop a central black `bull's eye’
