Ceftaroline was tested against 9,268 Staphylococcus aureus from 33 US hospitals.
•Susceptibility results were stratified by infection type and resistance profile.
•Ceftaroline susceptibility ranged from 95.4% (pneumonia) to 98.5% (SSSI).
•Ceftaroline retained potent and broad-spectrum activity against MRSA (93.4%S).
•Highest ceftaroline MIC value was 2 mg/L.
AbstractCeftaroline and comparators were tested against 9,268 Staphylococcus aureus isolates from 33 United States hospitals (2018−2020). Ceftaroline (MIC50/90, 0.25/1 mg/L) susceptibility ranged from 95.4% (pneumonia) to 98.5% (skin and skin structure) and was 97.2% overall. Ceftaroline retained potent and broad-spectrum activity against methicillin-resistant isolates, with a 93.4% overall susceptibility.
