Trytone Yeast Soy Extract (TYSE) Agar
Based on Listeria Enrichment Broth, originally intended as a selective enrichment broth, and solidified with added Agar this is a medium for the cultivation of Listeria spp from food and environmental samples.
NB: – Although this product will sustain the growth of Listeria spp it is not a selective medium and is not therefore recommended as a means of primary isolation when possible contaminating organisms may be present.
