  text: Active regulation of gene expression, orchestrated by complex interactions
    of activators and repressors at promoters, controls the fate of organisms. In
    contrast, basal expression at uninduced promoters is considered to be a dynamically
    inert mode of nonfunctional “promoter leakiness,” merely a byproduct of transcriptional
    regulation. Here, we investigate the basal expression mode of the mar operon,
    the main regulator of intrinsic multiple antibiotic resistance in Escherichia
    coli, and link its dynamic properties to the noncanonical, yet highly conserved
    start codon of marR across Enterobacteriaceae. Real-time, single-cell measurements
    across tens of generations reveal that basal expression consists of rare stochastic
    gene expression pulses, which maximize variability in wildtype and, surprisingly,
    transiently accelerate cellular elongation rates. Competition experiments show
    that basal expression confers fitness advantages to wildtype across several transitions
    between exponential and stationary growth by shortening lag times. The dynamically
    rich basal expression of the mar operon has likely been evolutionarily maintained
    for its role in growth homeostasis of Enterobacteria within the gut environment,
    thereby allowing other ancillary gene regulatory roles to evolve, e.g., control
    of costly-to-induce multidrug efflux pumps. Understanding the complex selection
    forces governing genetic systems involved in intrinsic multidrug resistance is
    crucial for effective public health measures.

  text: Several promising strategies based on combining or cycling different antibiotics
    have been proposed to increase efficacy and counteract resistance evolution, but
    we still lack a deep understanding of the physiological responses and genetic
    mechanisms that underlie antibiotic interactions and the clinical applicability
    of these strategies. In antibiotic-exposed bacteria, the combined effects of physiological
    stress responses and emerging resistance mutations (occurring at different time
    scales) generate complex and often unpredictable dynamics. In this Review, we
    present our current understanding of bacterial cell physiology and genetics of
    responses to antibiotics. We emphasize recently discovered mechanisms of synergistic
    and antagonistic drug interactions, hysteresis in temporal interactions between
    antibiotics that arise from microbial physiology and interactions between antibiotics
    and resistance mutations that can cause collateral sensitivity or cross-resistance.
    We discuss possible connections between the different phenomena and indicate relevant
    research directions. A better and more unified understanding of drug and genetic
    interactions is likely to advance antibiotic therapy.

abstract:
- lang: eng
  text: Evolutionary adaptation is a major source of antibiotic resistance in bacterial
    pathogens. Evolution-informed therapy aims to constrain resistance by accounting
    for bacterial evolvability. Sequential treatments with antibiotics that target
    different bacterial processes were previously shown to limit adaptation through
    genetic resistance trade-offs and negative hysteresis. Treatment with homogeneous
    sets of antibiotics is generally viewed to be disadvantageous, as it should rapidly
    lead to cross-resistance. We here challenged this assumption by determining the
    evolutionary response of Pseudomonas aeruginosa to experimental sequential treatments
    involving both heterogenous and homogeneous antibiotic sets. To our surprise,
    we found that fast switching between only β-lactam antibiotics resulted in increased
    extinction of bacterial populations. We demonstrate that extinction is favored
    by low rates of spontaneous resistance emergence and low levels of spontaneous
    cross-resistance among the antibiotics in sequence. The uncovered principles may
    help to guide the optimized use of available antibiotics in highly potent, evolution-informed
    treatment designs.
