Cholera HiVeg™ Medium Base is recommended for selective isolation of Vibrio species from specimens heavily contaminated with Enterobacteriaceae. Addition of Potassium Tellurite and sodium lauryl sulphate makes media selective . Sodium chloride enhances growth of all species. Sodium lauryl sulphate inhibits many contaminating organisms. Potassium tellurite inhibits many gram positive and gram negtaive organisms. This medium is prepared by replacing animal peptones with vegetable defined peptones to avoid BSE/TSE/GMO risk.
