Antibiotics with less reliable but occasional (depending on isolate and subspecies) activity: occasionally penicillins including penicillin, ampicillin and ampicillin-sulbactam, amoxicillin and amoxicillin-clavulnate, and piperacillin-tazobactam (not all vancomycin-resistant Enterococcus isolates are resistant to penicillin and ampicillin)
Amoxicillin is an antibiotic while clavulanic acid is a non-antibiotic β-lactamase inhibitor which prevents metabolism of amoxicillin by certain bacteria. In addition to its β-lactamase inhibition, clavulanic acid shows central nervous system actions and effects and has been studied in the potential treatment of various psychiatric and ...
Gentamicin is a bactericidal antibiotic that works by binding the 30S subunit of the bacterial ribosome, negatively impacting protein synthesis. The primary mechanism of action is generally accepted to work through ablating the ability of the ribosome to discriminate on proper transfer RNA and messenger RNA interactions. [ 24 ]
Bacterial resistance to cephalosporins is often due to bacterial production of β-lactamase enzymes that deactivate these antibiotics. Avibactam inhibits some (but not all) bacterial β-lactamases. Also, some bacteria are resistant to cephalosporins by other mechanisms, and therefore avibactam doesn't work.

Narrow-spectrum antibiotics have low propensity to induce bacterial resistance and are less likely to disrupt the microbiome (normal microflora). [3] On the other hand, indiscriminate use of broad-spectrum antibiotics may not only induce the development of bacterial resistance and promote the emergency of multidrug-resistant organisms, but also cause off-target effects due to dysbiosis.
