Ceftobiprole activity against Gram-positive and Gram-negative pathogens causing bone and joint infections in the United States from 2016 to 2020.
Diagnostic microbiology and infectious disease(2022)
摘要
Bone and joint infections (BJIs) present significant treatment challenges. Ceftobiprole, a broad-spectrum cephalosporin with activity against methicillin-resistant Staphylococcus aureus, is approved in many European and other countries for the treatment of adults with community- and hospital-acquired pneumonia, excluding ventilator-associated pneumonia. In this study, the in vitro activity of ceftobiprole and comparators was evaluated against clinical isolates collected from BJIs in the USA from 2016 to 2020. Gram-positive pathogens made up 70.6% of all BJI isolates and included S. aureus (47.4% of all isolates), β-hemolytic streptococci, coagulase-negative staphylococci, and Enterococcus faecalis. Ceftobiprole was highly active against S. aureus (MIC50/90 values, 0.5/1 mg/L; 99.6% susceptible using the European Committee on Antimicrobial Susceptibility Testing susceptibility breakpoint of ≤2 mg/L for the treatment of pneumonia patients) and exhibited potent activity against the other Gram-positive cocci and the predominant BJI Gram-negative groups. These results support the further evaluation of ceftobiprole for this potential indication.
