Enterococcus Selective Agar (Enterococcosel Agar) is basically the same as Enterococcosel Broth (Cat. 1204) to which has been added 1,2% agar. It is a sensitive enrichment medium for the isolation of streptococci from specimens containing numerous other flora. Many organisms such as saprophytic Neisseria, Staphylococcus, Haemophilus, non-hemolytic streptococci, and a certain number of Enterobacteriaceae are inhibited wholly or partially, permitting satisfactory fluorescence studies of Group A streptococci in 18 24 hours. Casein and Soy peptones provide essential nutrients for growth. Dextrose is the fermentable carbohydrate energy source. Sodium chloride maintains the osmotic balance. Sodium citrate provides additional carbon. Sodium azide is an inhibitor. Sodium sulfite when reduced produces H2S. L-Cystine lowers the oxidation-reduction potential by removing oxygen to maintain a low Eh. Crystal violet is a pH indicator. Bacteriological agar is the solidifying agent.
