  1. *Samples for culture sensitivity were taken from a swab as deep as possible during the follow-up visits upon the presence of signs/symptoms of infection. Tissue samples (e.g. bone or fascia) were taken in the operation room under general anesthesia in case of revision/debridement. Species confirmation was performed using Vitek® System
  2. ±One isolate was methicillin- susceptible Staphylococcus hominis, the other was methicillin- resistant Staphylococcus epidermidis. The species of the other two isolates were not identified, but one was methicillin resistant and the other was methicillin susceptible
  3. &Assessment for Mycobacterium tuberculosis was performed for patients with signs/symptoms and/or history of tuberculosis infection
