EC Medium with MUG is used for the fluorogenic detection of Escherichia coli in a laboratory setting. EC Medium with MUG is not intended for use in the diagnosis of disease or other conditions in humans.
EC Medium was developed by Hajna and Perry in an effort to improve the methods for the detection of the coliform group and E. coli. This medium consists of a buffered lactose broth with the addition of 0.15% Bile Salts Mixture. Growth of spore-forming bacteria is inhibited by the bile salts, while growth of E. coli is enhanced by its presence. EC Medium with MUG is the same formula as EC Medium, with the addition of 4-methylumbelliferyl-β-D-glucuronide. Feng and Hartman developed a rapid assay for E. coli by incorporating 4-methylumbelliferyl-β-D-glucuronide (MUG) into Lauryl Tryptose Broth at a final concentration of 100 µg/mL. Moburg determined the amount of MUG could be reduced to a final concentration of 50 µg/mL without adversely affecting results.
EC Medium with MUG is prepared according to the formula specified by US EPA and methods for water and food testing.
