A 65-year-old woman has a long-term central venous catheter for intravenous therapy. She develops fever and subsequently has multiple blood cultures positive for Staphylococcus epidermidis. All of the S. epidermidis isolates have the same colony morphology and antimicrobial susceptibility pattern, suggesting that they are the same strain. In what possible way do you think she has contracted the bacteria? Which link in the chain of infection has broken in this particular scenario and what will be your advice to avoid such infections?
