(WSBT) Staph is the shortened name for Staphylococcus (pronounced: staf-uh-low-kah-kus), a type of bacteria. These bacteria can live harmlessly on many skin surfaces, especially around the nose, mouth, genitals, and anus. But when the skin is punctured or broken for any reason, staph bacteria can enter the wound and cause an infection.

There are more than 30 species in the staph family of bacteria, and they can cause different kinds of illnesses — for example, one kind of staph can cause urinary tract infections. But most staph infections are caused by the species Staphylococcus aureus (S. aureus).

S. aureus most commonly causes skin infections like folliculitis, boils, impetigo, and cellulitis that are limited to a small area of a person's skin. S. aureus can also release toxins (poisons) that may lead to illnesses like food poisoning or toxic shock syndrome.

For more information on staph infections, (i.e. how do people get staph infections, what are the signs of staph infections, and preventing staph infections) go to www.kidshealth.org.
