    Dynamic post-translational modification profiling of Mycobacterium tuberculosis-infected primary macrophages

    Jonathan M Budzik et al.
    Measurement of post-translational modifications in primary macrophages infected with Mtb revealed phosphorylation of TAX1BP1, an autophagy receptor that enables full maturation of the Mtb autophagosome.

    Genomic adaptations in information processing underpin trophic strategy in a whole-ecosystem nutrient enrichment experiment

    Jordan G Okie et al.
    Trait-based metagenomic analysis of an ecosystem fertilization experiment shows that genomic traits that affect the costs and rates of biochemical information-processing mediate community assembly.

    Potential impact of outpatient stewardship interventions on antibiotic exposures of common bacterial pathogens

    Christine Tedijanto et al.
    Antibiotic stewardship in the outpatient setting can substantially reduce exposures of potential pathogens to common antibiotics, and complementary efforts are needed to reduce remaining exposures that occur in 'necessary' contexts.

    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 gut bacterial amyloid promotes α-synuclein aggregation and motor impairment in mice

    Timothy R Sampson et al.
    Production of an amyloid protein by bacteria within the gut microbiome can influence the pathophysiology of a mouse model of synucleinopathy.

    High fat diet induces microbiota-dependent silencing of enteroendocrine cells

    Lihua Ye et al.
    Enteroendocrine cells sense nutrients in the gut and regulate digestive physiology but are rendered insensitive following fat ingestion due to alteration of gut microbiota.

    Intestinal infection regulates behavior and learning via neuroendocrine signaling

    Jogender Singh, Alejandro Aballay
    Feedback from the intestine during infection can modulate the behavior, learning, and microbial perception of the host.

    Multistability and regime shifts in microbial communities explained by competition for essential nutrients

    Veronika Dubinkina et al.
    Multistability and regime shifts are common and species diversity is high in microbial communities when nutrient supplies are balanced and competing species have different stoichiometries of essential nutrients.

    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.

    NHR-14 loss of function couples intestinal iron uptake with innate immunity in C. elegans through PQM-1 signaling

    Malini Rajan et al.
    Nuclear receptor NHR-14 regulates the subcellular localization of the zinc transcription factor PQM-1 to coordinate innate immunity with iron sequestration during pathogen infection in C. elegans..
