However, some can make you sick. A person that has been exposed to these bacteria may have an upset stomach, vomiting, fever, or diarrhea. Children and the elderly are more at risk from these bacteria. Coliform bacteria are microbes found in the digestive systems of warm-blooded animals, in soil, on plants, and in surface water.

The majority of the enteric plating media developed in the early years of the 20 century utilized either mixtures of bile salts or individual salts as selective agents to achieve inhibition of gram-positive species. In , Endo reported the development of a culture medium for the differentiation of lactose fermenters from the nonfermenters in which no bile salts were used.
Inhibition of gram-positive microorganisms was achieved by the sodium sulfite and basic fuchsine contained in the formulation. It was developed initially in order to facilitate the isolation and identification of the typhoid bacillus. The original formula has been modified extensively since its introduction. The meat infusions have been replaced by a peptic digest of animal tissue. The dye composition and concentration also have been adjusted. Over the years, Endo Agar has been an important medium in the microbiological examination of potable water and wastewater, dairy products and foods; however, the current compendia of standard methods for the examination of these materials recommend alternative media formulations.
It is classified as only slightly selective since other media contain more potent inhibitors of the gram-positive microorganisms. Product details. Order form. Endo Agar Base. Selected quantity: 0.
