Is penicillin G narrow spectrum?

While penicillin G is a narrow-spectrum antibiotic, it is reliably active against many gram-positive pathogens that cause IE, most notably streptococci and enterococci. Penicillin G resistance may occur in streptococci and enterococci through alterations in the PBPs that decrease the binding affinity of penicillin.
