- is a coagulase negative, gram positive organism;
- has emerged as one of the most common organisms in total joint infections (and in other implanted devices);
- it is often minimally toxic (as compared to other bacterial infections), and many patients will have minimal symptoms of infection;
- it is particularly prone to recurrence following joint replantation;
- ref: Infection in total joint replacements. Why we screen MRSA when MRSE is the problem?
- biofilm and colonization of implants:
- its high recurrence rate may be related to its propensity to form a biofilm layer (extra-cellular glycocalyx) which coats the bacteria, which protects by engulfment by neutrophils;
- slime layer may make antibiotic penetration and bacteria eradication more difficult;
- Adherence of Staphylococcus epidermidis to biomaterials is augmented by PIA.
