STREPTOCOCCUS ENRICHMENT BROTH (SE BROTH) (VEG.)

This medium is prepared by using vegetable peptones in place of animal based peptones which make the medium free of BSE/TSE risks. Streptococcus Enrichment Veg Broth is the modification of the Streptococcus Enrichment Broth (S.E. Broth). Rochaix first observed the ability of Enterococci to hydrolyse esculin. Enterococci can hydrolyze esculin but other Streptococci fail to do so. Presumptive identification of group D Streptococci by bile esculin test was reported by Facklam and Moody. Later on Bile Esculin Medium was modified by Isenberg et al by reducing the bile concentration and adding sodium azide to the medium

for enrichment of Streptococci
