Listeria Selective HiVeg™ agar (Twin Pack) is recommended for selective isolation and cultivation of Listeria species from clinical specimens. Thiaminium dichloride is the vitamin B source added to improve the growth of Listeria. Thiocyanate and Nalidixic acid inhibits gram-negative bacteria. Listeria species grows luxuriantlly on this medium. This medium is prepared by replacing animal peptones with vegetable defined peptones to avoid BSE/TSE/GMO risk.
