Staph epidermidis


- Discussion:
    - 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;
    - 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;
    - controversies:
            - treatment of staph implant related infection:
            - in the report by Konig et al, the authors report on the success of a single case of staph epi infection over an orthopaedic implant
                      with a combination of rifampin and cipro;
            - references: 
                      - Treatment of staphylococcal implant infection with rifampicin-ciprofloxacin in stable implants.

- Treatment:
      - vancomycin
      - zyvox
