Abstract

Ceftriaxone is used to treat oxacillin-susceptible S. aureus (OSSA) prosthetic joint infection (PJI). Susceptibility of ceftriaxone against OSSA has been questioned. Ceftriaxone susceptibility was determined against 100 PJI OSSA isolates. Ceftriaxone MIC90/MIC50 were 8/4 and 4/3μg/mL by broth microdilution and Etest, respectively. Ceftriaxone susceptibility is inferable by oxacillin susceptibility.

Keywords: Ceftriaxone; Oxacillin-susceptible Staphylococcus aureus; Prosthetic joint infection.
