Blood Agar Base is a general-purpose, enriched culture medium used for the preparation of Blood Agar plates after supplementation with sterile defibrinated blood (usually 5–10% sheep or horse blood). It supports the growth of fastidious organisms and allows for the detection and differentiation of hemolytic patterns — including alpha (α), beta (β), and gamma (γ) hemolysis. This medium is essential in clinical microbiology, veterinary labs, food safety, and pharmaceutical quality control.
Key Features:
-
Designed for optimal blood incorporation without affecting gel clarity or pH stability
-
Differentiates hemolytic activity of organisms on the basis of red blood cell lysis
-
Supports a wide range of bacteria, including Streptococcus, Staphylococcus, Listeria, and others
-
Free of selective inhibitors, allowing for unbiased growth of sensitive pathogens
Applications:
-
Preparation of Blood Agar plates for detecting hemolysis (α, β, γ)
-
Isolation and identification of clinically important pathogens, especially streptococci
-
Use in clinical and diagnostic laboratories
-
Pharmaceutical and food microbiology quality control
