- Endo agar (also called Endo's medium) is a microbiological growth medium with a faint pink colour. Originally developed for the isolation of Salmonella typhi, it is now used mostly as a coliform medium. Most gram-negative organisms grow well in this medium, while growth of gram-positive organisms is inhibited.

Jan 3, 2022 · Endo was successful in inhibiting gram-positive bacteria on his medium by the incorporation of sodium sulfite and basic fuchsin. The resulting Endo Agar, also known as Fuchsin Sulphite and Infusion Agar, was used to isolate the typhoid bacilli.

Mar 12, 2024 · Some gram-positive bacteria can grow on Endo agar: The sodium sulfite in Endo agar can inhibit the growth of some gram-positive bacteria, but not all. For example, some strains of Staphylococcus aureus can grow on Endo agar.
Jan 23, 2022 · One notable feature of Endo Agar is that it inhibits gram-positive bacteria without the use of bile salts, which were traditionally employed for this purpose. Instead, Endo achieved inhibition by incorporating sodium sulfite and basic fuchsin into the medium.
PRINCIPLE. Meat peptone supplies essential amino acids, peptides, and nitrogenous compounds necessary for bacterial growth. Lactose is the fermentable carbon source. Dipotassium phosphate is a buffer. Sodium sulfite and basic fuchsin suppress gram-positive organisms.
Jun 10, 2021 · MacConkey agar is another example of a Selective & differential medium, it is used to isolate & distinguish between Gram-negative enteric rods. MacConkey agar contains bile salts and crystal violet that inhibit Gram positive bacteria but allow the growth of Gram negative bacteria.
