Oxoid™ Eosin Methylene Blue (EMB) Agar (500g) is a selective and differential medium designed for the isolation and differentiation of Gram-negative enteric bacteria, particularly coliforms and Escherichia coli, from clinical, food, and environmental samples. The dyes eosin and methylene blue inhibit Gram-positive organisms and also serve as indicators of lactose fermentation.
