Modified Dixon's agar (mDixon)

Applications:

Dixon's agar is mainly used for growing Malassezia furfur, but a modified variant (mDixon) can also be used for growing other dermatophytes.

The medium contains:

• malt extract (contains nutrients)
• peptone (enzymatic degradation products of animal tissue or milk, which are also a sources of various nutrients)
• desiccated beef bile, which contains various bile acids
• Tween 40
• glycerol monooleat, which is a source of oleic acid
• agar (gelifying agent)
• H₂O

The pH of the medium should be 6.0.

Other comments:

Most Malassezia species (except M. pachydermatis) are lipophilic i.e. they require the addition of lipids to the culture medium. Other dermatophytes can also be grown in mDixon.
