Abstract
mecA-positive Staphylococcus aureus isolates phenotypically susceptible to cefoxitin (mecA-methicillin-sensitive S. aureus [MSSA]) have been identified. We describe the treatment and outcomes among patients with mecA-MSSA bloodstream infections (BSI) and MRSA BSI matched 1:1 for age, BSI origin, and BSI type (n = 17 per group). Compared to MRSA BSI patients, mecA-MSSA BSI patients more often experienced clinical failure (58.8% and 11.8%, P = 0.010), driven largely by persistent bacteremia (35.3% and 11.8%). mecA-MSSA BSI patients may be at higher risk for poor clinical outcomes.
