Müller-Hinton agar is a microbiological growth medium that is commonly used for antibiotic susceptibility testing. It is also used to isolate and maintain ''Neisseria'' and ''Moraxella'' species. It typically contains (w/v): *30.0% beef infusion *1.75% casein hydrolysate *0.15% starch *1.7% agar *pH adjusted to neutral at 25 °C. Five percent sheep blood and nicotinamide adenine dinucleotide may also be added when susceptibility testing is done on ''Streptococcus'' species. This type is also commonly used for susceptibility testing of ''Campylobacter''. It has a few properties that make it excellent for antibiotic use. First of all, it is a non-selective, non-differential medium. This means that almost all organisms plated on here will grow. Additionally, it contains starch. Starch is known to absorb toxins released from bacteria, so that they cannot interfere with the antibiotics. Second, it is a loose agar. This allows for better diffusion of the antibiotics than most other plates. A better diffusion leads to a truer zone of inhibition. ==References== 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「Mueller-Hinton agar」の詳細全文を読む スポンサード リンク
