Description

Presumptively identify group D Streptococci and Enterococci using solid Bile Esculin Agar (Dehydrated) medium.

Presumptively identify group D Streptococci and Enterococci using Thermo Scientific™ Remel™ Bile Esculin Agar (Dehydrated). Esculin agar containing 40% bile, correlated well with serologically confirmed group D streptococci as reported by Swan1. Using Swan's formula, Facklam and Moody tested over 700 strains of Streptococci and Enterococci representing all known serological groups and found all strains to be bile-resistant and esculin-positive2. Meyer et al. found that 61 of 62 strains of Enterococci hydrolyzed esculin in a medium containing bile3.

This medium contains Oxgall in a concentration of 4% (equivalent to 40% bile) that inhibits most strains of Streptococci and Enterococci other than group D. In the presence of bile, group D Streptococci and Enterococci 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.
