Predictive information for staphylococci: oxacillin/methicillin-resistant isolates

Oxacillin/Methicillin-resistant staphylococci are resistant to all beta-lactam antibiotics EXCEPT ceftaroline.  Contact the Microbiology Laboratory at 984-974-1830 to request ceftaroline susceptibility testing.  Fluoroquinolones are not indicated for the treatment of staphylococcal infections, including MRSA.  Beta-lactams include penicillin, ampicillin, amoxicillin, oxacillin, nafacillin, ticarcillin, piperacillin, and any penicillin/beta lactamase inhibitor combinations such as amoxicillin/clavulanic acid, ampicillin/sulbactam, ticarcillin/clavulanic acid, pipercillin/tazobactam.  Beta lactams also include cephalosporins (such as cefazolin, cefepime, cefotaxime, ceftazidime, and ceftriaxone), aztreonam, and carbapenems (such as imipenem, meropenem, and ertapenem).
