Bile Esculin Azide Agar, 90 mm Monoplate

Isolate, enumerate, and presumptively identify group D streptococci and enterococci using Thermo Scientific™ Bile Esculin Azide Agar, a microbiological media that includes a high portion of Ox bile. Compliant to ISO7899-2, the medium can be used to confirm Entercocci from Slanetz Bartley Medium. Ox bile present in the media inhibits the growth of Gram-positive bacteria except Enterococci, while sodium azide suppresses the Gram-negative bacteria. Group D streptococci and enterococci are able to hydrolyze esculin into aesculetin and glucose, and the bondage of aesculetin and ferric ammonium citrate causes the brown-black to black halo around the colonies.

• Selective Isolation: Specifically formulated to enhance the growth of Enterococcus species while inhibiting non-target organisms, ensuring accurate and reliable results.
• Differential Properties: Contains bile and aesculin to provide clear differentiation of Enterococci through characteristic blackening of colonies.
• Compliance with ISO Standards: Meets stringent ISO requirements, offering consistent performance and reliability for microbiological testing.
• Enhanced Inhibition: Azide effectively suppresses Gram-negative bacteria, providing a highly selective environment for Enterococci. 

The bile esculin azide agar is a selective medium used in water application (Confirmation test) for the isolation and identification of genus Streptococcus, particularly group D streptococci. The presence of bile salts and esculin azide in the medium ensures selective isolation of the target organisms. The bile esculin test is a crucial technique in microbiology for identifying bacteria capable of hydrolyzing esculin. The medium's composition, including agar and bile salts, supports the growth of specific bacteria while inhibiting others.

In the field of microbiology, the identification and isolation of bacteria are essential for diagnosing diseases and understanding bacterial behavior. The use of selective media, such as bile esculin agar, plays a significant role in this process. The presence of sodium azide and bile salts in the medium ensures the selective growth of target organisms, aiding in the accurate identification of bacteria.

The study of bacteria, including streptococci and other organisms, is vital for understanding various diseases and their impact on humans. Research in clinical microbiology focuses on the identification, isolation, and characterization of bacteria to develop effective treatments and preventive measures. The use of selective media, such as bile esculin azide agar, is an essential technique in this research.

In the laboratory, the use of high-quality media and diagnostic products is crucial for obtaining reliable results. The combination of manual, semi-automated, and fully automated test products offered by Thermo Scientific ensures that laboratories have the tools they need for accurate identification and isolation of bacteria. The presence of bile salts, esculin azide, and other selective agents in the media supports the growth of specific bacteria, aiding in the identification process.
