GranuCult^?modified Tryptic Soy Broth

半岛bd体育手机客户端 说明

一般描述

mTSB (modified Tryptic Soy Broth) without the addition of novobiocin is a selective enrichment media for the isolation and growth of non-O157 Shiga Toxin-ProducingEscherichia coli(STEC) andSalmonellafrom meat products, carcass, and environmental sponges. For the selective enrichment ofEscherichia coliO157:H7 in outbreak-related samples, e.g. fermented sausage, cooked meat products, the addition of novobiocin is recommended. Pancreatic digest of casein, papaic digest of soybean meal, and casamino acids (casein acid hydrolysate) serve as carbon and nitrogen sources, vitamins, and minerals. Glucose also serves as a carbon energy source for rapid growth during the enrichment. Sodium chloride maintains the osmotic balance and dipotassium hydrogen phosphate acts as a buffering agent for maintaining the pH balance of the medium. The addition of Bile salts ensures selectivity of the media.

应用

modified Tryptic Soy Broth has emerged as the medium of choice for the enrichment ofE. coliandSalmonellaspecies in red meats. This medium is not intended for use in the diagnosis of a disease or other conditions in humans.

特点和优势

mTSB media renders the isolation simpler, less costly, and substantially suppresses the growth of other gram-negative Enterobacteriaceae species by 90%.
