What are skin fungi ?

There are hundreds of thousands of types of fungi in the world.  This immense class of organisms can be found in the air, in the soil, in plants and on the bodies of animals and humans.  Fungi constitute the mold on bathroom tiles, the yeast responsible for the fermentation of wine and beer, and of course the gourmet mushrooms we like to find on our plates.

Athlete’s feet

Fungal infections between the toes are very common, particularly in hot countries.  The warmth and moisture produced (between the fourth and fifth toes especially) provide an ideal environment for the development of fungi.  They multiply and cause itching, maceration of the skin (the outer layer of the skin absorbs water, turns white and sloughs off); later, painful cracks appear. 

Body fungal infections

Fungus infections of the body caused by dermatophytes are common among children who come into close contact with pets.  These infections appear as scaly flat rings with red edges and pale centers.  The rings grow and cover large areas of the body, including the face.

Nail fungi

The incidence of fungus infections of the nails increases with age.  It usually begins with the toenails, and after a number of years may migrate to the fingernails.  Most patients who suffer from fungus infections of the toenails also suffer from athlete’s foot, the symptoms of which are maceration and cracks of the skin and an intense itch.  The affected nails are usually thick and yellow, with flaking upper surfaces.
