Reliably susceptible:
Penicillin
Amoxicillin/Ampicillin
Vancomycin.
Resistant to Cephalosporins.
Variably susceptible: Fluoroquinolones.
Aminoglycosides may be used for synergy in specific infections ie infective endocarditis if no high-level resistance. If urinary isolate, most are nitrofurantoin susceptible
