What is a Fungal Nail?
Description and Tips
Onychomycosis is an infection of the bed and plate underlying the surface of the nail, and is caused by various types of fungi, which are commonly found throughout the environment. Fungi are simple parasitic plant organisms, such as molds and mildew, that lack chlorophyll and therefore do not require sunlight for growth. A group of fungi called dermatophytes easily attack the nail, thriving off keratin, the nail's protein substance.
