Thermo Scientific™ Remel™ Bile Esculin Azide Agar

Description

• Selectively isolate and presumptively identify group D Streptococci and Enterococci using Thermo Scientific™ Remel™ Bile Esculin Azide Agar (Dehydrated)
• Esculin agar containing 40% bile, correlated well with serologically confirmed group D streptococci as reported by Swan 1
• Isenberg et al
• modified the formulation by reducing the concentration of bile and adding the selective agent, sodium azide 2
• In the presence of bile, group D S treptococci and E nterococci hydrolyze esculin and form esculetin and dextrose
• Ferric ammonium citrate supplies ferric ions which react with esculetin and form brown-black colonies on Bile Esculin Agar
• Selective solid media - Selective agents like sodium azide and 1% Oxgall inhibit B acilli and most gram-positive bacteria other than group D S treptococci and Enterococci
• Easy-to-read – black-brown colonies of group D Streptococci and Enterococci are easy to read.
