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
