Now the medium of choice for the routine isolation of clinically significant anaerobes, our medium supports the growth of most fastidious anaerobes. Classical colony formation, odour and fluorescence under UV are diagnostic features on this medium. The choice of peptones and growth factors provide early growth of most organisms whilst the starch has an important role as a de-toxification agent. The medium is often made selective for various groups of anaerobes by the addition of appropriate selective agents.
For susceptibility testing
At ECCMID 2018 a poster was presented outlining the work towards the development of a EUCAST disk diffusion method for rapidly growing anaerobic bacteria using fastidious anaerobe agar (FAA).
'Conclusion: FAA is a reliable medium for disk diffusion of anaerobic bacteria when using agar from at least three manufacturers.'
BioConnections is one of those manufacturers
