Differentiation of Group D from non-Group D Streptococci.

Bile Esculin Agar is prepared according to the formula specified by Swan, and later evaluated by Facklam and Moody. It was concluded that the bile esculin test provided a reliable means of identifying enterococci and differentiation from non-enterococci. Enterococci are bile tolerant and hydrolyze esculin which imparts a dark brown color to the medium. Gram positive bacteria other than enterococci are inhibited by the bile salts.
