- Polysaccharide capsule allows adherence to prosthetic devices.
|Culture and Detection|
- Blood cultures are frequently contaminated with S. epidermidis as needle passes through the skin. Generally, consider a S. epidermidis bactermia if blood draws from two separate places grow the organism.
- In healthy individuals S. epidermidis is part of the normal skin flora. The organism results in clinical disease only in patients possessing prosthetic devices to which the bacteria can easily adhere.
- Possible Pathologies
