Bacterial skin infections are quite common. As the largest organ in the human body, the skin is the front-line defense against dangerous organisms. It is also home to a healthy balance of good and bad bacteria, which usually cause little drama until an imbalance in the skin’s defenses creates the opportunity for unfriendly bacteria to wreak havoc. When this happens, the results range from mildly annoying to fatal.

1. Furuncles and Carbuncles

Commonly known as boils, furuncles, pus-filled follicular infections, and carbuncles, collections of boils, can appear on any part of the body. If they’re large enough, they may contain infected pus that a doctor must drain and lance. Boils occur when bacteria multiply under the skin too quickly for the immune system to kill them off. They can go away on their own, or the individual may need antibiotics.
