Skin Disorder by Infections

Acne, or acne vulgaris, the most common skin diseases, is a skin condition thought to be secondary to hormonal changes of adolescence. Folliculitis, on the other hand, is caused by infection of hair follicles by staphylococci. The condition is sometimes called barber’s its, because individuals with beard tend to have deeper hair follicles that are more likely to be affected by bacteria. Furuncles (boils) and carbuncles are deeper and more serious infection of hair follicles, resulting in abscess formation.

Streptococcal pyoderma, or impetigo, and erysipelas are contagious infections caused by the entry of certain strains of streptococcal bacteria into breaks in the skin. Streptococcal pyoderma is characterized by the formation of localized crusty lesions. Erysipelatous lesions are usually widely spreading zones of redness, swelling, and blistering in the skin. Erysipelas is accompanied by systemic effects, including chills and fever; certain forms can rapidly involve large areas of the skin and can cause prostration and death.

Ringworm of the scalp (tinea cruris, or “jock itch”) are fungal infections of the skin. The term ringworm arises from the circular form of the lesions. Dermatophytosis of the foot, or “athlete’s foot,” is also caused by a fungus. Fungal infections are often accompanied by itching, burning, stringing, and seepage of tissue fluids at the site of infection.

Scabies and pediculosis are common parasitic infections. Scabies is caused by mites that burrow into the skin upper the epidermis layer. The mites excretion of waste products into the skin causes intense itching, especially at night. Adults often acquire scabies by sleeping with or having sexual relations with an infected person. Pediculosis is a louse infestation of the scalp, trunk, or pubic area (“crabs”). Each of the three kinds is caused by a different species of louse.

The most common viral infections of skin are herpes complex (cold sore or fever sore) and herpes zoster (shingles). Warts are another form of viral infection. Several types of warts occurs on different parts of the body, each one caused by a particular type of virus.
