    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.

    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.

    Predictable properties of fitness landscapes induced by adaptational tradeoffs

    Suman G Das et al.
    Adaptational tradeoffs constrain the evolutionary pathways towards antimicrobial resistance, but highly fit mutants are nevertheless likely to arise at any concentration of the drug.

    Mapping microbial ecosystems and spoilage-gene flow in breweries highlights patterns of contamination and resistance

    Nicholas A Bokulich et al.
    Mapping microbial landscapes in indoor environments can predict how contaminants and spoilage resistance genes propagate within food-production environments, yielding novel insight for controlling spoilage.

    Species-wide whole genome sequencing reveals historical global spread and recent local persistence in Shigella flexneri

    Thomas R Connor et al.
    Shigella flexneri, globally the most frequent cause of bacterial dysentery, is far more diverse, and has caused disease around the world for far longer than other Shigella species by persisting in local environments over extended timescales.
