Community-acquired strains are often susceptible to penicillinase-resistant penicillins (eg, methicillin, oxacillin, nafcillin, cloxacillin, dicloxacillin), cephalosporins, carbapenems (eg, imipenem, meropenem, ertapenem), tetracyclines, macrolides, fluoroquinolones, trimethoprim / sulfamethoxazole (TMP / SMX), gentamicin, vancomycin, and teicoplanin.
