Spectrum of activity describes how many species of microbes a drug works against. Broad-spectrum antibiotics are effective against many different groups of bacteria, while narrow-spectrum antibiotics work well against a particular group or species, but have little effect on the rest. Based on our class results, which of the following are narrow-spectrum? Group of answer choices Amoxicillin/Clavulanic acid Ampicillin Kanamycin Ciprofloxacin Vancomycin Bacitracin Trimethoprim/Sulfamethoxazole

Gram-negative genera used (listed first): Escherichia, Pseudomonas, Serratia.
Gram-positive genera used (listed last): Bacullus, Staphylococcus, Enterococcus.
There was no class data for the response of E. faecalis to Bacitracin.
Antibiotic abbreviations: AmC is amoxicillin/clavulanic acid, AM in ampicillin, B is bacitracin, CIP is ciprofloxacin,
NB is novobiocin, SXT is trimethoprim/sulfamethoxazole, and Va is vancomycin.
