BD Difco™ Tetrathionate Broth Base
Tetrathionate Broth Base is used as a selective enrichment medium for the isolation of Salmonella from feces, urine, foods, and other materials of sanitary importance.
- Peptones provide nitrogen, vitamins, amino acids, and carbon
- Oxgall inhibits Gram-positive microorganisms
- Calcium carbonate neutralizes and absorbs toxic metabolites
Tetrathionate, which is formed in the medium by the addition of the iodine-iodide solution, inhibits the normal intestinal flora of fecal specimens.
