Product Details
A 5% Sheep Blood Agar Plate, also known as Sheep Blood Agar (SBA), is a culture medium commonly used in microbiology laboratories. It is a nutrient-rich agar supplemented with 5% sheep blood, typically obtained from aseptically collected sheep blood.
The addition of sheep blood to the agar serves multiple purposes:
Enrichment: The presence of blood provides additional nutrients, growth factors, and enzymes that support the growth of a wide range of microorganisms.
Differential Properties: Sheep Blood Agar can help differentiate bacteria based on their hemolytic activity. Hemolysis refers to the lysis or destruction of red blood cells by certain bacterial enzymes. The different patterns of hemolysis can provide important information for the identification and classification of bacteria.
a. Alpha Hemolysis: Partial hemolysis that appears as a greenish discoloration around bacterial colonies.
b. Beta Hemolysis: Complete hemolysis that results in a clear zone around bacterial colonies, indicating the complete destruction of red blood cells
c. Gamma Hemolysis: No hemolysis or change in the appearance of the blood agar around bacterial colonies.
The 5% Sheep Blood Agar Plate is frequently used for various purposes, including the isolation and identification of pathogenic bacteria, particularly those associated with respiratory infections, such as Streptococcus pneumoniae and Streptococcus pyogenes.
The medium provides a favorable environment for bacterial growth and allows for the observation of distinct hemolytic patterns, aiding in the differentiation and identification of bacterial species based on their hemolytic characteristics.
