Activity of ceftobiprole against Staphylococcus spec. isolates derived from foreign body associated infections.

Antibiotic therapy is essential in foreign body associated infections. The treatment regime should aim at high tissue concentrations, high bioavailability, high biofilm penetration and good tolerance. We investigated whether the new cephalosporin ceftobiprole is active against clinical isolates from musculoskeletal foreign body associated infections. One hundred ninety-six staphylococci isolates (coagulase negative staphylococci and Staphylococcus aureus) derived from foreign body associated infections were tested towards susceptibility to ceftobiprole, using a test strip assay and broth microdilution. The MIC for all strains S. aureus indicated susceptibility to ceftobiprole. The MIC of only two strains of coagulase negative staphylococci was above 2 mg/L. Our results show that ceftobiprole might be considered as an off-label treatment option in foreign body associated infections.
