Rosenow devised an excellent medium for culturing streptococci by supplementing Dextrose Broth with bovine brain tissue. Hayden, revising Rosenow's procedure by adding crushed marble to the medium, reported favorable growth of organisms from dental pathogens. Brain-Heart Infusion Solids was developed as an alternative to bovine based Brain Heart Infusion containing media, replacing calf brain and beef heart with porcine brains and hearts. Brain-Heart Infusion Solids can replace traditional bovine based BHI media in most applications.
The nutritionally rich formula of Brain-Heart Infusion Solids is used to grow a variety of microorganisms. The original Brain-Heart Infusion media are specified in standard methods for multiple applications
