  2. Eosin methylene blue - Wikipedia

    en.wikipedia.org/wiki/Eosin_methylene_blue

    E. coli on EMB agar. Eosin methylene blue (EMB, also known as "Levine's formulation") is a selective and differential media used for the identification of Gram-negative bacteria, [1] specifically the Enterobacteriaceae. EMB inhibits the growth of most Gram-positive bacteria. EMB is often used to confirm the presence of coliforms in a sample.

  3. Buffered charcoal yeast extract agar - Wikipedia

    en.wikipedia.org/wiki/Buffered_charcoal_yeast...

    Buffered charcoal yeast extract (BCYE) agar is a selective growth medium used to culture or grow certain types of bacteria, particularly the Gram-negative species Legionella pneumophila. [1] It has also been used for the laboratory diagnosis of Acanthamoeba keratitis , [ 2 ] Francisella and Nocardia spp .

    Then, either MacConkey agar or EMB agar (or both) are inoculated with the stool. On MacConkey agar, deep red colonies are produced, as the organism is lactose-positive, and fermentation of this sugar will cause the medium's pH to drop, leading to darkening of the medium. Growth on EMB agar produces black colonies with a greenish-black metallic ...

  5. Coliform bacteria - Wikipedia

    en.wikipedia.org/wiki/Coliform_bacteria

    An easy way to differentiate between different types of coliform bacteria is by using an eosin methylene blue agar plate. [12] This plate is partially inhibitory to Gram (+) bacteria, and will produce a color change in the Gram (-) bacterial colonies based on lactose fermentation abilities. [12]

  6. Thayer–Martin agar - Wikipedia

    en.wikipedia.org/wiki/Thayer–Martin_agar

    Thayer–Martin agar (or Thayer–Martin medium, or VPN agar) is a Mueller–Hinton agar with 5% chocolate sheep blood and antibiotics. It is used for culturing and primarily isolating pathogenic Neisseria bacteria , including Neisseria gonorrhoeae and Neisseria meningitidis , as the medium inhibits the growth of most other microorganisms.

  7. Mueller–Hinton agar - Wikipedia

    en.wikipedia.org/wiki/Mueller–Hinton_agar

    Mueller Hinton agar is commonly used in the disk diffusion method, which is a simple and widely used method for testing the susceptibility of bacterial isolates to antibiotics. In this method, small disks impregnated with different antibiotics are placed on the surface of the agar, and the zone of inhibition around each disk is measured to ...

  8. Endo agar - Wikipedia

    en.wikipedia.org/wiki/Endo_agar

    Endo agar. Endo agar (also called Endo's medium) is a microbiological growth medium with a faint pink colour. [1] 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. [2]

  9. VRBD agar - Wikipedia

    en.wikipedia.org/wiki/VRBD_agar

    VRDBA, VRDB Agar, or Violet Red Bile Dextrose Agar, is a microbiological growth medium. [1] It can be used in agar plates to monitor or assess bacterial growth in the laboratory, particularly the growth of Enterobacteriaceae , for which it is selective.
