Streptococcus Selection HiVeg™ Broth is recommended for selective cultivation of all types of Streptococci, including group A beta haemolytic strains. Sodium azide, sodium sulphite inhibits gram-negative rods and the crystal violet suppresses Staphylococci. Growth of coliforms, Proteus, Pseudomonas and Bacillus species is markedly suppressed in this medium. Streptococcus Selection HiVeg™ Broth is prepared by using vegetable peptones in place of animal based peptones which make the media free of BSE/TSE risks.
