Definition

By Mayo Clinic staff

Staph infections are caused by staphylococcus bacteria, a type of germ commonly found on the skin or in the nose of even healthy individuals. Most of the time, these bacteria cause no problems or result in relatively minor skin infections.

But staph infections don't always remain skin-deep. In some circumstances, they may invade your bloodstream, urinary tract, lungs or heart.

Severe staph infections usually occur in people who are already hospitalized or who have a chronic illness or weakened immune system. But it is possible for otherwise healthy people to develop life-threatening staph infections.
