Thermo Scientific™ Triple Sugar Iron Agar (TSI) Medium (Dehydrated)

Description

• Differentiate gram-negative enteric bacilli such as Enterobacteriaceae on the basis of dextrose, lactose and sucrose fermentation and hydrogen sulfide production using Thermo Scientific™ Triple Sugar Iron Agar (TSI) (Dehydrated)
• The sucrose content in this medium permits the recognition and exclusion of sucrose-fermenting species
• These organisms may ferment lactose slowly, or not at all, during the incubation period, but they attack sucrose readily
• Some Proteus and other species may give similar reactions to salmonellae and shigellae , and it is necessary to distinguish them by their ability to hydrolyse urea
• Triple Sugar Iron Agar should be used in parallel with Urea Broth or Urea Agar
• TSI Agar is available as dehydrated culture medium or in ready-to-use prepared media tubes and in formats that meet international industrial guidelines for microbiological testing
• Not all products are available for sale in all territories
