Specifications

Tryptose Agar is recommended for the cultivation and isolation of pathogenic and saprophytic bacteria, especially Brucella as specified by Huddleson and Castaneda (1,2) Huddleson found Tryptose media to be equal or superior to meat infusion media, providing uniformity for the cultivation and differentiation of fastidious organisms (1).
Catalog #T9050
The successful isolation of Brucella spp. supports the use of Tryptose media as a rich general purpose media. Tryptose Agar is prepared with Tryptose, which is a mixed enzymatic hydrolysate with rich nutritional value for microbiological culture media. The enzymatic hydrolysis of Tryptose permits the preservation of vitamins and amino acids.
