Ceftobiprole activity against multidrug-resistant Staphylococcus aureus clinical isolates collected in the United States from 2016 through 2022
Abstract
ABSTRACT Ceftobiprole was recently approved by the United States (US) Food and Drug Administration (FDA) for the treatment of adult patients with Staphylococcus aureus bacteremia, including right-side endocarditis, acute bacterial skin and skin structure infections, and community-acquired bacterial pneumonia in adults and pediatrics. Ceftobiprole is an advanced-generation cephalosporin approved in many countries for the treatment of adults with community-acquired pneumonia and hospital-acquired pneumonia, excluding ventilator-associated pneumonia. We evaluated the activities of ceftobiprole and comparators against methicillin-resistant S. aureus (MRSA) and multidrug-resistant (MDR) S. aureus clinical isolates. A total of 19,764 S . aureus isolates were collected from patients with various infection types at 37 US medical centers from 2016 to 2022. Susceptibility testing was performed by broth microdilution according to Clinical and Laboratory Standard Institutes (CLSI) standards. Isolates were categorized as MDR if they were nonsusceptible by CLSI criteria to ≥3 antimicrobials. Ceftobiprole was highly active against MRSA ( n = 8,184; MIC 50/90 , 1/2 mg/L; 99.3% susceptible [S]) and MDR ( n = 2,789; MIC 50/90 , 1/2 mg/L; 98.1%S) isolates and retained activity against 87.3% of ceftaroline-nonsusceptible isolates ( n = 433; MIC 50/90 , 2/4 mg/L). Ceftobiprole demonstrated greater susceptibility rates than ceftaroline against all resistant subsets. Ceftobiprole was highly active…
