Heart Infusion Broth | Nutrient‑Rich Medium for Fastidious Microorganisms | AS‑1247
Heart Infusion Broth
Highly Nutritious Broth for Fastidious Microorganisms
Heart Infusion Broth (HIB) is a rich, non-selective, general-purpose liquid medium formulated for the cultivation and propagation of fastidious microorganisms. It is widely used in blood culture work and related clinical microbiology applications, and is suitable for organisms such as streptococci, pneumococci, meningococci, and other nutritionally demanding bacteria.
Why Labs Use HIB
Pneumococci
Meningococci
Other fastidious bacteria
⚠️ Important: Heart Infusion Broth vs Brain Heart Infusion Broth
A classic, highly nutritious broth based on heart infusion, intended for cultivation of a wide range of fastidious organisms and commonly recommended for blood culture work.
A related but distinct enriched medium containing both brain and heart infusions, often described as even broader in scope for fastidious and non-fastidious organisms, including many aerobic and anaerobic bacteria.
🔬 Technical Overview & Principle
Heart Infusion Broth is a non-selective enriched liquid medium developed to support organisms with demanding nutritional requirements. Official product literature describes it as a highly nutritious and well-buffered medium that supports growth of a wide variety of organisms, particularly fastidious bacteria. :contentReference[oaicite:1]{index=1}
Historically, infusion media derived from animal tissue were among the earliest rich media used in bacteriology, and modern Heart Infusion Broth continues that role by providing a concentrated nutrient environment for the propagation and maintenance of clinical isolates and other delicate organisms. :contentReference[oaicite:2]{index=2}
Heart infusion contributes soluble growth factors and organic nutrients, while the broth system provides a uniform, well-buffered liquid environment suitable for recovery, propagation, and routine cultivation of fastidious organisms.
🧪 Typical Functional Composition
🧫 Typical Laboratory Use Workflow
Reconstitute the dehydrated medium according to your validated laboratory method and sterilise as required for broth media preparation.
Use aseptic technique to inoculate with the target isolate or clinical material where an enriched, non-selective broth is appropriate.
Incubation temperature, atmosphere, and duration depend on the organism and laboratory protocol. The broth is especially suited to fastidious organisms requiring enriched nutrition. :contentReference[oaicite:8]{index=8}
Following growth, the broth culture may be used for subculture, maintenance, or other downstream microbiological procedures consistent with validated methods.
