  • Resistance to penicillin and newer narrow-spectrum β-lactamase-resistant penicillin antimicrobial drugs (e.g., methicillin, oxacillin) appeared soon after they were introduced into clinical practice in the 1940s and 1960s, respectively ( 4 ). (cdc.gov)
  • Penicillin or ampicillin plus an aminoglycoside is usually effective against all these organisms. (nih.gov)
  • Penicillin or ampicillin and an aminoglycoside combination may also be used in the initial therapy of late-onset sepsis as in cases with early-onset sepsis. (nih.gov)
