The misuse of antibiotics has led to the development and spread of antibiotic
resistance in clinically important pathogens. These resistant infections are
having a significant impact on treatment outcomes and contribute to approximately
25,000 deaths in the U.S. annually. If additional therapeutic options are not
identified, the number of annual deaths is predicted to rise to 317,000 in North
America and 10,000,000 worldwide by 2050. Identifying therapeutic methodologies
that utilize our antibiotic arsenal more effectively is one potential way to
extend the useful lifespan of our current antibiotics. Recent studies have
indicated that modulating metabolic activity is one possible strategy that can
impact the efficacy of antibiotic therapy. In this review, we will address recent
advances in our knowledge about the impacts of bacterial metabolism on antibiotic
effectiveness and the impacts of antibiotics on bacterial metabolism. We will
particularly focus on two studies, Lobritz, et al. (PNAS, 112(27): 8173-8180) and
Belenky et al. (Cell Reports, 13(5): 968-980) that together demonstrate that
bactericidal antibiotics induce metabolic perturbations that are linked to and
required for bactericidal antibiotic toxicity.
