MITIS SALIVARIUS AGAR BASE (VEG.)

Description

This medium is developed by using Veg hydrolysate and Veg peptone which are free of BSE/TSE risks. Mitis Salivarius Veg Agar Base is the modification of Mitis Salivarius Agar Base which is prepared as described by Chapman for the isolation of Streptococci from mixed cultures showing alpha and gamma reactions on Blood Agar. This medium (with 1% potassium tellurite) is highly selective medium which enables to isolate Streptococci from highly contaminated specimens like exudates from body cavities and faeces etc., as it inhibits a wide variety of bacteria. Some authors have also used sodium azide in this medium to inhibit the growth of gram-negative bacteria like Proteus. Beta-haemolytic Streptococci produce colonies that resemble Streptococcus mitis.
