Product Summary and Explanation
Tetrathionate Broth Base is used as a selective enrichment for the cultivation of Salmonella spp. that may be present in small numbers and compete with intestinal flora. Salmonella organisms may also be injured in food-processing procedures, which include exposure to low temperatures, sub-marginal heat, drying, radiation, preservative, and sanitizers. Salmonella spp. cause many types of infections, from mild self-limiting gastroenteritis to life-threatening typhoid fever.
Mueller demonstrated the effectiveness of Tetrathionate Broth for enriching typhoid and paratyphoid bacilli while inhibiting coliform organisms. Using modified Mueller’s broth, Kauffmann increased the number of positive isolates. Tetrathionate Broth was used in studies for the poultry industry and in a collaborative study for rapid screening of Salmonella in food. Tetrathionate Broth Base, abbreviated as TT Broth Base, is specified in standard methods for Salmonella testing. The FDA, Bacteriological Analytical Manual incorporate Tetrathionate Broth Base as a pre-enrichment medium for detecting Salmonella in food materials. Tetrathionate Broth Base is used in processing fecal cultures for bacteria.
