Streptococcus Selection Agar 500G

Streptococcus Selection Agar is recommended for selective isolation and enumeration 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.
