[A quantitative method for the evaluation of keratinophilic fungi of environmental origin].

A tentative quantitative method is proposed to evaluate keratinophilic flora in the environment (soil and sand). It associates the MPN methodology to the "hair bait" technique. The methodology developed on sand samples has been able to detect shores with high amounts of keratinophilic flora (Focene, Torvaianica) besides clean areas.
