What causes ringworm?
Although the world is full of yeasts, molds, and fungi, only a few cause skin problems. These agents are called the dermatophytes (which means "skin fungi"). An infection with these fungi is medically known as dermatophytosis. Skin fungi can only live on the dead layer of keratin protein on top of the skin. They rarely invade deeper into the body and cannot live on mucous membranes, such as those in the mouth or vagina.
Scientific names for the most common of the dermatophyte fungi that cause ringworm include Trichophyton rubrum, Trichophyton tonsurans, Trichophyton interdigitale, and/or Trichophyton mentagrophytes, Microsporum canis, and Epidermophyton floccosum.
