Brain-Heart Infusion Broth is used for the cultivation of a wide variety of fastidious organisms in a laboratory setting. Brain-Heart Infusion Broth is not intended for use in the diagnosis of disease or other conditions in humans.
Rosenow prepared a rich medium for culturing streptococci by combining dextrose broth and brain tissue. Hayden modified the original formula while working with dental pathogens. The current formula is a modification of Rosenow and Hayden, using dehydrated infusions of porcine brain and heart tissue.
Brain-Heart Infusion Broth can be supplemented with antibiotics, varying amounts of sodium chloride, yeast extract, and serum to provide a rich medium for bacteria, yeasts and pathogenic fungi. The addition of 0.1% agar can be used to lower oxygen tension, providing an atmosphere to support the growth of aerobic, microaerophilic, and obligate anaerobic microorganisms.
Brain-Heart Infusion Broth, abbreviated as BHI, is specified in many references for food and water testing.
