Thayer-Martin agar (or Thayer-Martin medium) 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. When growing ''Neisseria meningitidis'', one usually starts with a normally sterile body fluid (blood or CSF), so a plain chocolate agar is used. Thayer-Martin agar was initially developed in 1964, with an improved formulation published in 1966. ==Components== It usually contains the following combination of antibiotics, called VCN inhibitor *Vancomycin, which is able to kill most Gram-positive organisms, although some Gram-positive organisms such as ''Lactobacillus'' and ''Pediococcus'' are intrinsically resistant *Colistin, which is added to kill most Gram-negative organisms except ''Neisseria'', although some other Gram-negative organisms such as ''Legionella'' are also resistant *Nystatin, which can kill most fungi *Trimethoprim, which inhibits Gram-negative organisms, especially swarming ''Proteus'' 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Thayer-Martin agar」の詳細全文を読む スポンサード リンク
