Sodium Azide Crystal Violet Blood Agar is used for selective cultivation of Erysipelothrix rhusiopathiae.

  • Sodium chloride maintains the osmotic balance of the medium
  • Can also be used for the isolation of Streptococci especially Streptococcus pneumoniae
  • Crystal violet and sodium azide inhibit most of the gram-positive and gram-negative bacteria

Sodium Azide Crystal Violet Blood Agar is prepared based on the formula described by Packer for selective cultivation of Erysipelothrix rhusiopathiae . It can also be used for the isolation of Streptococci especially Streptococcus pneumoniae. Beef heart infusion and casein enzymic hydrolysate provide the necessary nitrogenous compounds and other essential nutrients to the organisms. Glucose is the fermentable carbohydrate source in the medium but is weakly fermented by Erysipelothrix rhusiopathiae without the gas production. Crystal violet and sodium azide inhibit most of the gram-positive and gram-negative bacteria respectively. Blood provides the growth factors and also aid to detect the haemolytic reaction if any. Sodium chloride maintains the osmotic balance of the medium.
