Where is staph epidermidis found?

Is part of the resident normal flora and it can cause subacute endocarditis. Normally we have it everywhere on the skin, but the growth has also a slime (or biofilm). staph epidermidis is at peace with my body, but it will take opportunity of the introduction of catheters, valve replacements or knee prosthetic joint. And on these surfaces the bacteria will spread by bacteremia, and attach itself to these foreign objects.
