Brain-Heart Infusion Agar is used for the cultivation of a wide variety of fastidious organisms in a laboratory setting. Brain-Heart Infusion Agar 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 pork brain and pork heart tissue.
Brain-Heart Infusion Agar can be supplemented with antibiotics, varying amounts of sodium chloride, yeast extract and serum to provide a rich medium for bacteria, yeast, and pathogenic fungi. Brain-Heart Infusion Agar (BHI Agar), is specified in many references for food and water testing. Standard Methods for the Examination of Water and Wastewater recommends Brain-Heart Infusion media in tests for the verification of fecal streptococci.
