The basal body of the type-III secretion system of Yersinia enterocolitica within bacterial membranes shows elasticity and is longer than related isolated systems.

An experimentally constrained model shows that Escherichia coli faces fitness trade-offs in chemotaxis behaviors, and that adaptation of phenotypic diversity through altered gene regulation permits populations to resolve these trade-offs.

The deer mouse (Peromyscus) has emerged as a model system for studying many aspects of biology, supported by extensive historical knowledge of its fascinating and varied natural history.

The crystal structure of Pur-alpha in complex with DNA reveals its molecular mechanisms of nucleic-acid binding and unwinding, allowing for a better understanding of its essential role in neurons.

A network of the gut chemical landscape predicts microbe-mediated biotransformation of foods and drugs and supports the generation of mechanistic hypotheses of microbiome metabolic phenotypes that shape human biology.

In situ structural analysis of bacterial flagellar motor in the Lyme disease spirochete reveals novel conformational change driven by proton motive force.

The corkscrew-like motility of Spirochete bacteria is enabled by a unique, asymmetrically constructed flagellum that wraps around the cell body within the periplasm.

In the absence of human FcgRIIb function, an infection with Borrelia burgdorferi triggers enhanced autoreactive immune responses in humanized mice in vivo.

In situ structures of the flagellar motors genetically docked in CCW and CW rotational states reveal major rearrangement that facilitates rotational switch in Vibrio alginolyticus..

A conceptual and unifying framework with a critical appraisal of lipid hijacking by microbes cycling between an arthropod vector and a mammalian host is explored.
