CRITERION™ Tetrathionate Broth Base, Dehydrated Culture Media, 2kg Bucket

Hardy Diagnostics CRITERION™ Tetrathionate Broth Base for the selective enrichment of Salmonella spp., used for microbiological testing of foods such as, raw milk or other highly contaminated samples or specimens

Note: Tetrathionate Supplement, product #Z129 (Iodine-Iodide Solution) is required for this medium.

Proteose peptone acts as a nutritive base. The tetrathionate together with the sodium thiosulfate, iodide, and calcium carbonate, all work as selective agents to commensal fecal flora, but the most important of these is tetrathionate. Salmonella species that are capable of reducing tetrathionate will proliferate in this medium.

CRITERION™ Tetrathionate Broth Base conforms to the formulation recommended by the American Public Health Association (APHA), the Food and Drug Administration (FDA), and The United States Pharmacopeia (USP)
