Re-examining cephalosporin activity against methicillin-susceptible <i>Staphylococcus aureus</i> among clinical isolates from southern Taiwan

Cephalosporin non-susceptibility can occur among MSSA isolates. Although elevated oxacillin MICs were associated with higher MICs for several cephalosporins, this relationship was less predictive for ceftaroline. These findings highlight microbiological variability in MSSA cephalosporin susceptibility and may inform situations where direct MIC testing provides additional clarity.
