m-Endo Agar

Description

m-Endo Agar is used for the enumeration of coliforms in water by the membrane filtration method in a laboratory setting. m-Endo Agar is not intended for use in the diagnosis of disease or other conditions in humans.

The coliform group, especially Escherichia coli, are used as indicators of fecal pollution in water, for assessing the effectiveness of water treatment and disinfection, and for monitoring water quality. m-Endo Agar is prepared according to the formula of McCarthy, Delaney, and Grasso, and used in testing water for coliforms by a two-step membrane filtration procedure. Lauryl Tryptose Broth is used as the preliminary enrichment, resulting in higher coliform counts.
