Overview of Bacterial Skin Infections
Introduction
The skin provides a remarkably good barrier against bacterial infections. Although many bacteria come in contact with or reside on the skin, they are normally unable to establish an infection. When bacterial skin infections do occur, they can range in size from a tiny spot to the entire body surface. They can range in seriousness as well, from harmless to life threatening. Bacterial skin infections develop when bacteria enter through hair follicles or through small breaks in the skin that result from scrapes, punctures, surgery, burns, sunburn, animal or insect bites, wounds, and pre-existing skin disorders. People can develop bacterial skin infections after participating in a variety of activities, for example, gardening in contaminated soil or swimming in a contaminated pond, lake, or ocean.
