Principle And Interpretation

Staphylococcus Broth is recommended for the cultivation of Staphylococci from clinical and nonclinical specimens. It is a nutritive medium providing enough nutrients for the growth of Staphylococci. Standard Staphylococcus HiVeg™ Broth is prepared by completely replacing animal based peptone with vegetable peptones to avoid BSE/TSE risks associate with animal peptones. HiVeg™ peptone and yeast extract supply essential growth factors such as nitrogen, carbon, sulphur, vitamins and trace nutrients. Sodium chloride maintains the osmotic balance of the medium.
