Endo HiVeg Agar with NaCl, 2.5KG

Endo HiVeg™ agar w/ NaCl is used for detection and isolation of pathogenic enteric bacilli. Gram-negative bacteria can be differentiated on the basis of lactose fermentation, while inhibiting gram-positive bacteria. Sodium sulphite and basic fuchsin inhibits most of the gram-positive bacteria. Lactose fermenting Escherichia coli and coliforms produce aldehyde and acid. The aldehyde liberates fuchsin from the fuchsin-sulphite complex and colonies of lactose fermenters appear dark red. Non-lactose fermenters such as Salmonella show colorless colonies. Escherichia coli exhibits a permanent greenish metallic luster (fuchsin luster) to the colonies due to crystallization of fuchsin. This medium is prepared by replacing animal peptones with vegetable defined peptones to avoid BSE/TSE/GMO risk.
