Epidermophyton floccosum

What is Epidermophyton floccosum?

Epidermophyton floccosum is a species of fungus in the genus Epidermophyton. It is a common cause of dermatophytosis, or ringworm, infection of the skin. It is usually found in the keratin-rich areas of the skin, hair, and nails. This fungus thrives in moist areas, and is found primarily on the feet, scalp, and nails.

What Are the Symptoms of Epidermophyton Floccosum?

Epidermophyton floccosum can cause a wide variety of symptoms, though the most common are:

  • Reddish or light discolored patches of skin that spread to form a circular or ring-like shape
  • Scaly, itchy patches of skin
  • Hair loss
  • Brittle, dry, or thickened nails
  • Darkened skin

Diagnosis and Treatment

Epidermophyton infections can be diagnosed through a physical examination and the use of laboratory tests such as a potassium hydroxide (KOH) preparation, a culture test, and a fungal stain test. Once the diagnosis is made, treatment is generally a topical antifungal cream, powder, or lotion, depending on the location and severity of the infection.


The best way to prevent Epidermophyton floccosum infection is to practice good hygiene, including:

  • Wearing appropriate footwear, such as shower shoes, in public showers or locker rooms
  • Not sharing items such as combs, brushes, towels, or clothing with others
  • Immersing feet in antifungal foot baths
  • Avoiding tight-fitting shoes that can trap moisture and increase the risk of infection
