Fungi are spread far and wide in our environment. In nature, one may find them in soil, water as well as on plants and animals. Of the roughly 50,000 different species belonging to the realm of fungi, fewer than 300 species have been made responsible for infections in humans. Among the pathogenic species, fewer than a dozen cause far more than 90% of infections.
What are fungal infections?
Fungi infections of the skin are termed dermatomycosis and belong to the most frequently occurring diseases. Roughly 25% of the population are afflicted with them. A precondition for most infections is an impaired immune response of the person concerned, as well as a shift in the balance of the natural skin flora. Causes for this can be manifold.
When a fungus finds such favourable conditions, nothing stands in the way of a spread. How deeply a fungus can penetrate into the skin depends, when the skin is intact, on the type of fungus. Many fungi can only find optimum conditions for themselves directly in the horny layer of the skin, or on hair and nails, as they prefer tissue containing keratin.
When the immune system’s defence is intact, the fungi are unable to intrude into living cell material. Some fungi are able to migrate from the outside to the inside through the various layers of the epidermis and to even deeper-lying areas. Others manage to reach the true skin via the hair-shafts. Open wounds facilitate a spread into the skin’s deeper-lying layers. Usually, the result of a fungi invasion is a person’s subsequent inflammatory reaction.
