Bile Esculin Agar- Composition, Principle, Preparation, Results, Uses


Bile Esculin Agar (BEA) is a type of culture medium that is used in microbiology to isolate and identify certain bacteria, especially those belonging to the genus Enterococcus. Enterococci are gram-positive cocci that are commonly found in the gastrointestinal tract of humans and animals, and can cause various infections such as urinary tract infections, endocarditis, and bacteremia. Enterococci were formerly classified as group D streptococci, but they were reclassified in their own genus in 1984 based on molecular and biochemical criteria.
