    Bacterial survival in microscopic surface wetness

    Maor Grinberg et al.
    A new intricate reciprocity between microbiology and physics results in collective protection from desiccation through differential formation of stable microdroplets around bacterial aggregates on surfaces drying under moderate humidity.

    Asymmetric random walks reveal that the chemotaxis network modulates flagellar rotational bias in Helicobacter pylori

    Jyot D Antani et al.
    Asymmetric forward and backward swimming speeds reveal that the rotational bias, and not reversal frequencies, is an appropriate measure of chemotaxis signaling in Helicobacter pylori..

    BipA exerts temperature-dependent translational control of biofilm-associated colony morphology in Vibrio cholerae

    Teresa del Peso Santos et al.
    Vibrio cholerae uses a conserved ribosome assembly factor to repress biofilm formation at low temperatures.

    Adaptive tuning of mutation rates allows fast response to lethal stress in Escherichia coli

    Toon Swings et al.
    Population mutation rates are highly flexible and evolvable under extreme stress conditions, matching changes in selective pressure to avoid extinction of the entire population.

    Functional role of the type 1 pilus rod structure in mediating host-pathogen interactions

    Caitlin N Spaulding et al.
    The helical rod structure and dynamic spring-like properties of the type 1 pilus are evolutionarily fine-tuned for functioning in host-pathogen interactions during urinary tract infection and gut colonization.

    Antimicrobial peptide expression in a wild tobacco plant reveals the limits of host-microbe-manipulations in the field

    Arne Weinhold et al.
    The attempt to manipulate a microbiome in planta to study the ecological consequences under field conditions leaves plants and their microbes surprisingly unimpressed.

    Impaired respiration elicits SrrAB-dependent programmed cell lysis and biofilm formation in Staphylococcus aureus

    Ameya A Mashruwala et al.
    The absence of oxygen prompts Staphylococcus aureus cells to rupture resulting in increased formation of biofilms, which are the etiological agents of recurrent infections.
