Product Code: LAB060
This medium was developed in 1914 for the isolation of Salmonella typhi; other media have since proved superior for this purpose, but Endo agar has a role as a coliform medium.
It is recommended by the American Public Health Association as a standard medium for the enumeration of coliforms in water and dairy products. In this medium acetaldehyde is produced by coliforms and then fixed by the sulphite to produce a metallic sheen with the basic fuchsin dye. Most enteric Gram negative organisms will grow well, whilst Gram positive
organisms are mostly inhibited.
