A previously unrecognized group of metalloenzymes enables human gut microbes to metabolize dietary molecules and neurotransmitters and likely mediates interactions and metabolism among environmental microorganisms.

Shifts in pH that result from metabolic interactions between members of the Drosophila gut microbiota were sufficient to modulate Lactobacillus plantarum tolerance to the antibiotics rifampin and erythromycin.

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.

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.

The helical bacterium Helicobacter pylori patterns cell wall synthesis using two distinct cytoskeletal proteins, CcmA and MreB, to achieve its characteristic shape.

Production of an amyloid protein by bacteria within the gut microbiome can influence the pathophysiology of a mouse model of synucleinopathy.

Class-A penicillin-binding proteins are dispensable for rod-like cell-shape but essential for mechanical integrity by sensing and repairing cell-wall defects locally, as investigated in the model system Escherichia coli.

A bioinformatics pipeline has annotated over 2,500 complete genomes of circular DNA viruses belonging to dozens of established and emerging viral families.

Biochemical analyses and the crystal structure of TtsA reveal fundamental insight into the mechanisms by which this muramidase recognizes its peptidoglycan substrate to facilitate typhoid toxin secretion.

Giardia, a multi-ciliated parasitic protist, maintains four different flagellar lengths by balancing flagellar length-independent IFT-mediated assembly with length-dependent kinesin-13 mediated disassembly.
