Thermo Scientific™ SIM Medium (Dehydrated)

Description

• Differentiate enteric bacteria on the basis of sulphide production, indole production and motility with Thermo Scientific™ Oxoid™ SIM Medium (Dehydrated)
• The medium contains sodium thiosulphate and ferrous ammonium sulphate, which together act as indicators for the production of hydrogen sulphide
• Tryptone incorporated into the medium is a tryptophan-rich peptone and is degraded by specific bacteria to produce indole
• The use of 0.35% agar in the medium results in the production of a semi-solid medium, ideal for the examination of motility
• A motility-indole medium has been found to be helpful in the identification of the Enterobacteriaceae; e.g
• in the differentiation of Klebsiella from Enterobacter and Serratia species 1
• For convenience, these two important tests have been combined with sulphide-production in one tube
• The production of hydrogen sulphide is a useful diagnostic test in the identification of enteric bacteria and is helpful in the differentiation between Salmonella and Shigella
• Typical reactions of organisms in SIM medium: Organism Motility H 2 S Indole Escherichia coli ATCC® 25922 V - + Proteus hauseri ATCC® 13315 + + + Shigella sonnei ATCC® 25931 - - - Not all products are available for sale in all territories
