Further Information
Intended use
FAA agar plate with 5% blood (Fastidious Anaerobe Agar) is a selective medium for primary isolation of the most significant clinical anarobe bacteries including nutritious micro organisms.
Principle
On this agar plate, most clinically significant anaerobic bacteria can grow. The mixture of peptones, vitamin K and succinate has been developed to ensure increased growth conditions. Hemein increases the pigmentation of P. melaninogenicus. Specific growth promoters are cysteine (F. necrophorum, P. acne, B. fragilis), arginine (Eubacterium spp.), Pyrophosphate (P. gingivalis, P. asaccharolyticus). The low level of glucose ensures minimal production of acid as well as alcohols, which would otherwise inhibit colony growth. The FAA agar plate can also be used to determine the resistance of anaerobic bacteria.
