Primary Outcome Measures :
  1. Cessation of spread or reduction in the size of the primary infection site lesion [ Time Frame: 48-72 hours ]
  2. Defervescence [ Time Frame: 48 - 72 hours ]

Secondary Outcome Measures :
  1. Severity of signs and symptoms of the primary infection site lesion [ Time Frame: up to day 84-98 (late follow-up visit) ]
  2. Clinical response rate - overall and for MRSA [ Time Frame: Day 10 (TOC visit), Day 15-21 (SFU/EOT visit) ]
  3. Microbiological response rate - overall and for MRSA [ Time Frame: Day 15-21 (SFU/EOT visit) ]
  4. Change in susceptibility testing of S. aureus [ Time Frame: Day 15-21 (SFU/EOT visit) ]
    Changes in susceptibility testing of S. aureus isolates from the original infection site to linezolid and JNJ-32729463

  5. Rate of recurrence and new infection in subjects with MRSA [ Time Frame: Day 35-49 and Day 84-98 ]
  6. Defervescence [ Time Frame: Day 4 (Visit 3) ]
  7. Cessation of spread or reduction in the size of the primary infection site lesion [ Time Frame: Day 4 (Visit 3) ]
