Dermatophytes are a part of skin flora. For example, when compared to the genomes of other sequenced fungi, Malassezia spp. genomes are enriched for lipase genes and depleted for carbohydrate-utilizing enzyme genes, which is consistent with the carbohydrate-deficient, lipid-rich environment of the skin. These distinctions could explain why Malassezia species dominate the adult skin mycobiome. That’s why some dermatophytes are considered good parasites. Also, if a dermatophyte wants to cause an infection, it has to enter through a cut or irritated skin, because the fungi microbiome of the skin exists only on the dry layer which gets shed so an infection can’t happen.
