Fungal Nail Infection Causes
Fungal nail infection is caused by three main classes of organisms: fungi that infect hair, skin, and nails and feed on nail tissue (dermatophytes), yeasts, and non-dermatophyte molds. All three classes cause the very similar early and chronic symptoms or appearances, so the visual appearance of the infection may not reveal which class is responsible for the infection. Dermatophytes (including Epidermophyton, Microsporum, and Trichophyton species) are, by far, the most common causes of fungal nail infection worldwide. Yeasts cause 8% of infections, and non-dermatophyte molds cause 2% of fungal nail infections.
