General Susceptibility

MSSA

  • Anti-staphylococcal penicillins (i.e. cloxacillin) and cephalosporins (i.e. cefazolin) are optimal agents for intravenous therapy of MSSA infections.

  • Variable susceptibility to TMP-SMX, Clindamycin, and Tetracyclines.

MRSA

  • By definition resistant to cloxacillin and cephalosporins.

  • Susceptible to vancomycin, daptomycin, and linezolid.

  • Variable susceptibility to TMP-SMX, Clindamycin, and Tetracyclines
