Each of the following statements concerning staphylococci is correct EXCEPT:

  •  Scalded skin syndrome caused by S. aureus is due to enzymatic degradation of epidermal desmosomes by catalase.
  •  The majority of clinical isolates of S. aureus produce penicillinase; therefore, penicillin G should not be used for antibiotic therapy for S. aureus infections.
  •  S. aureus is differentiated from S. epidermidis by the production of coagulase.
  •  S. aureus infections are often associated with abscess formation.
