The NYC (New York City) medium or GC (Neisseria gonorrhoeae) medium agar is a type of selective media used for isolating Gonococci and N. meningitidis. [ 1 ] The growth of Neisseria gonorrhoeae colonies on New York City medium agar
The test sample is homogenized in sterile 0.1% peptone water and diluted. 0.1ml volumes are transferred to the agar plate and spread across the surface. The agar plates are incubated at 22 °C for 48 hours aerobically. Typical colonies of Brochothrix thermosphacta will grow as straw-colored colonies, 0.5-1.0mm in diameter.
An agar plate – an example of a bacterial growth medium*: Specifically, it is a streak plate; the orange lines and dots are formed by bacterial colonies.. A growth medium or culture medium is a solid, liquid, or semi-solid designed to support the growth of a population of microorganisms or cells via the process of cell proliferation [1] or small plants like the moss Physcomitrella patens.

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 .
Blood agar plates (BAPs) contain mammalian blood (usually sheep or horse), typically at a 5–10% concentration. BAPs are enriched, and differential media is used to isolate fastidious organisms and detect hemolytic activity. β-Hemolytic activity will show lysis and complete digestion of red blood cell contents surrounding a colony.
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.
Agar plates Organisms are placed or streaked onto petri dishes Provides a solid surface for stationary growth, compact and stackable Agar based dipsticks Essentially miniature agar plates in the form of dipsticks Diagnostic purposes, can be used anywhere, cost effective, easy to use Selective and differential media
