Tryptose Broth is used for the cultivation of Brucella spp. and other fastidious microorganisms in a laboratory setting. Tryptose Broth is not intended for use in the diagnosis of disease or other conditions in humans.

Tryptose Broth is recommended for the cultivation and isolation of pathogenic and saprophytic bacteria. Historically, it was considered necessary to include meat extract or infusion as a nutritional supplement in culture media. However, tryptose was developed while studying growth requirements of Brucella spp. In these studies Huddleson found Tryptose media to be equal or superior to meat infusion media, providing uniformity for the cultivation and differentiation of fastidious organisms.

Tryptose Broth can be used a complete basal medium or supplemented with enrichment. Huddleson used a broth containing 2% Tryptose as an enrichment medium in the isolation of Brucella spp. from samples. McCullough et al. reported that addition of thiamine, dextrose, and iron salts increased growth of Brucella suis. Addition of 0.1% agar to Tryptose Broth can increase growth of aerobes and anaerobes in liquid media. Tryptose media are recommended in standard methods for food testing.
