    Global analysis of gene expression reveals mRNA superinduction is required for the inducible immune response to a bacterial pathogen

    Kevin C Barry, Nicholas T Ingolia, Russell E Vance
    Infected cells superinduce expression of mRNA in order to initiate an immune response to a bacterial pathogen that blocks host protein synthesis.

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

    Christine Tedijanto, Yonatan H Grad, Marc Lipsitch
    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.

    Trogocytosis-associated cell to cell spread of intracellular bacterial pathogens

    Shaun Steele, Lauren Radlinski ... Thomas H Kawula
    Live intracellular bacterial pathogens can transfer from infected cells to uninfected macrophages upon cell-to-cell contact.

    Microbiome-pathogen interactions drive epidemiological dynamics of antibiotic resistance: A modeling study applied to nosocomial pathogen control

    David RM Smith, Laura Temime, Lulla Opatowski
    A novel mathematical modeling framework for antibiotic-resistant bacteria combining within-host microbiome-pathogen interactions with population-level pathogen epidemiology, demonstrating how antibiotic consumption and ecological competition come together to drive the spread of resistance.

    Systematic detection of horizontal gene transfer across genera among multidrug-resistant bacteria in a single hospital

    Daniel R Evans, Marissa P Griffith ... Daria Van Tyne
    Mobile genetic elements were identified and tracked as they exchanged between multidrug-resistant bacteria causing infections at a single hospital.

    The intricate relationship of G-Quadruplexes and bacterial pathogenicity islands

    Bo Lyu, Qisheng Song
    Unveiling the intricate web of interactions between G4 structures and pathogenicity islands in 89 bacterial genomes significantly advances our understanding of bacterial virulence mechanisms.

    Counteracting suppression of CFTR and voltage-gated K+ channels by a bacterial pathogenic factor with the natural product tannic acid

    Yajamana Ramu, Yanping Xu ... Zhe Lu
    Tannic acid acts as an ‘antidote’ against the negative effects of a bacterial enzyme, which can both aggravate cystic fibrosis and enable the anthrax bacteria to evade the immune responses elicited by a typical live vaccine.

    Perforin-2 is essential for intracellular defense of parenchymal cells and phagocytes against pathogenic bacteria

    Ryan M McCormack, Lesley R de Armas ... Eckhard R Podack
    Perforin-2 deficiency is lethal upon infection with pathogenic bacteria despite the presence of other bactericidal effectors.

    Spatial and temporal coordination of Duox/TrpA1/Dh31 and IMD pathways is required for the efficient elimination of pathogenic bacteria in the intestine of Drosophila larvae

    Fatima Tleiss, Martina Montanari ... C Leopold Kurz
    Bacterial location quantifications highlights how Drosophila melanogaster larvae discriminate bacteria to isolate and later eliminate pathogens in the anterior midgut through coordinated mechanisms involving reactive oxygen species (ROS) and antimicrobial peptides (AMPs).
