MacConkey Agar without Salt

Originally introduced for the isolation and differentiation of Lactose & Non-Lactose Fermenting enteric organisms the medium in this case has been modified to improve the isolation of staphylococci and enterococci. The absence of Sodium Chloride provides a low electrolyte medium that prevents spreading of most Proteus spp. Although recommended for use in the examination of urine samples in clinical laboratories it has uses in Food, Water and Dairy applications.
