Insights on the etiopathogenesis of onychomycosis by dermatophyte, yeast and non-dermatophyte mould in ex vivo model.

Fungal biofilms have been involved in the pathogenesis of onychomycosis, but the aspects contributing to this association need to be enlightened. This study aimed to investigate the ability of three different fungi to form biofilm on the nail. All evaluated fungi were able to grow on the nails, using them as the only nutritional source and formed a structure strongly suggestive of biofilms.
