    Rapid decline of bacterial drug-resistance in an antibiotic-free environment through phenotypic reversion

    Anett Dunai et al.
    Drug-resistance declines in the laboratory in an antibiotic stress-free environment, indicating that restricting antimicrobial usage in the clinics could be a useful policy.

    Highly parallelized droplet cultivation and prioritization of antibiotic producers from natural microbial communities

    Lisa Mahler et al.
    This microscale cultivation strategy will help in the discovery of novel bacterial species and their prioritization for antibiotic screening campaigns.

    Antibiotics: Modelling how antimicrobial resistance spreads between wards

    Tjibbe Donker
    Moving patients between wards and prescribing high levels of antibiotics increases the spread of bacterial infections that are resistant to treatment in hospitals.

    Bacterial Evolution: The road to resistance

    Devon M Fitzgerald
    The way that bacteria grow—either floating in liquid or attached to a surface—affects their ability to evolve antimicrobial resistance and our ability to treat infections.

    Evolutionary pathways to antibiotic resistance are dependent upon environmental structure and bacterial lifestyle

    Alfonso Santos-Lopez et al.
    Bacteria growing in biofilms evolve antimicrobial resistance via different pathways and generate greater genetic diversity than well-mixed populations, selecting fitter but less resistant genotypes.

    Allosteric communication in class A β-lactamases occurs via cooperative coupling of loop dynamics

    Ioannis Galdadas et al.
    A combination of equilibrium and nonequilibrium molecular dynamics simulations is an effective tool to study allosteric communications in ultrafast enzymes that show little or no conformational changes.

    Impact of HIV co-infection on the evolution and transmission of multidrug-resistant tuberculosis

    Vegard Eldholm et al.
    HIV co-infection does not affect Mycobacterium tuberculosis mutation rates and does not drive the emergence of antimicrobial resistance within patients in the largest outbreak of multidrug-resistant tuberculosis in Latin America to date.

    RNA polymerase mutations cause cephalosporin resistance in clinical Neisseria gonorrhoeae isolates

    Samantha G Palace et al.
    Ceftriaxone resistance has arisen multiple times in clinical gonococcal populations via previously undescribed RNA polymerase mutations, underscoring the importance of continued surveillance for novel resistance determinants.

    A novel ciprofloxacin-resistant subclade of H58 Salmonella Typhi is associated with fluoroquinolone treatment failure

    Duy Pham Thanh et al.
    A fluoroquinolone resistant variant of Salmonella Typhi has emerged that is likely to be widespread in the Indian subcontinent; therefore fluoroquinolones should not be recommended for empirical typhoid fever therapy in this setting.

    Targeted surveillance strategies for efficient detection of novel antibiotic resistance variants

    Allison L Hicks et al.
    Sampling informed by pathogen genomic data may facilitate more efficient detection of novel antibiotic resistance than random sampling.
