Brain Heart Infusion Broth is used for the cultivation of a wide variety of fastidious organisms and is not intended for use in the diagnosis of disease or other conditions in humans.
A rich isotonic infusion medium with tryptose (a mixture of meat and milk peptones) providing a wide range of substrates. A low concentration of glucose is used to stimulate early growth. The medium is lightly buffered to prevent the early death of some species due to acid production. Organisms which produce significant amounts of acid may well overwhelm the buffering system and auto-sterilize. The medium is suitable for use as a blood culture medium or as an enrichment broth for fastidious organisms.
