    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.

    4-Hydroxy-2-nonenal antimicrobial toxicity is neutralized by an intracellular pathogen

    Hannah Tabakh et al.
    The aldehyde 4-hydroxy-2-nonenal is a novel component of the host antimicrobial reactive oxygen burst, and the bacterium Listeria monocytogenes encodes genes specifically for its detoxification.

    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.

    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.

    ODELAM, rapid sequence-independent detection of drug resistance in isolates of Mycobacterium tuberculosis

    Thurston Herricks et al.
    Time-lapse live cell imaging of single Mycobacterium tuberculosis bacilli growing into small colonies enables their rapid phenotypic characterization including anti-microbial resistance and heteroresistance in clinical isolates.

    Evolution of multifunctionality through a pleiotropic substitution in the innate immune protein S100A9

    Joseph L Harman et al.
    In the ancestor of mammals, a multifunctional innate immune protein evolved when a mutation enhanced the protein’s pro-inflammatory activity and proteolytic regulation without disrupting the protein’s antimicrobial activity.

    Quantifying antibiotic impact on within-patient dynamics of extended-spectrum beta-lactamase resistance

    Rene Niehus et al.
    A data-driven within-host model reveals that different antibiotics are associated with divergent effects on antibiotic resistance carriage and abundance in hospitalised patients, with important implications for antibiotic stewardship.

    Synergy and remarkable specificity of antimicrobial peptides in vivo using a systematic knockout approach

    Mark Austin Hanson et al.
    While antimicrobial cocktails are highly effective for defence against pathogenic microbes, the innate immune response may instead employ highly specific peptidic antibiotics to combat certain natural enemies.

    Multiple lineages of Streptomyces produce antimicrobials within passalid beetle galleries across eastern North America

    Rita de Cassia Pessotti et al.
    The widespread occurrence of metabolically active streptomycetes in Odontotaenius disjunctus beetle frass may insulate their galleries against pathogenic fungal invasion through the production of diverse antimicrobial specialized metabolites.

    The antibiotic bedaquiline activates host macrophage innate immune resistance to bacterial infection

    Alexandre Giraud-Gatineau et al.
    The anti-tuberculosis drug bedaquiline reprograms human macrophages into potent bactericidal phagocytes, which are able to control bacterial infection.
