Staphylococcus epidermidis is invariably present on normal human skin. It is nonpathogenic ordinarily but can cause disease when the host defences are breached. It is a common cause of stitch abscesses. It has a predilection for growth on implanted foreign bodies such as artificial heart valves, shunts, intravascular catheters and prosthetic appliances, leading to bacteremia. Hospital strains of Staphylococcus epidermidis are usually multiple drug resistant. Endocarditis may be caused,particularly in drug addicts.
