SPECIFICATION

 

  • Rosenow1 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 Rosenow1 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.
  • NCCLS, National Committee for Clinical Laboratory Standards, cites Brain-Heart Infusion Broth for preparing the inoculum used in antimicrobial susceptibility tests.
