Dermatophytosis is a clinical condition caused by fungal infection of the skin in humans, pets such as cats, and domesticated animals such as sheep, goats and cattle. Perhaps the most common term for the infection, "ringworm", is a misnomer, since the condition is caused by fungi of several different species and not by parasitic worms. The fungi that cause parasitic infection, collectively dermatophytes, feed on keratin, the material found in the outer layer of skin, hair, and nails.
Symptoms vary depending on where you’re infected. With a skin infection, you may experience red, itchy, scaly, or raised patches, patches that develop blisters or begin to ooze, patches that may be redder on the outside edges or resemble a ring, patches with edges that are defined and raised. If you’re experiencing dermatophytosis in your nails, they may become thicker, discolored, or begin to crack.
Doctors recommend medications as well few lifestyle changes. Doctor may prescribe various medications, depending on the severity of your ringworm infection. Ketoconazole is a prescription strength cream that is often used to treat fungal infections. Over-the-counter medications and skin creams may be recommended for use as well. Over-the-counter products may contain clotrimazole, miconazole, or other related ingredients.
Since before 1906 Dermatophytosis has been prevalent, at which time ringworm was treated with compounds of mercury or sometimes sulfur or iodine.
