This Week in Microbiology

TWiM explains the finding that owning a dog during adolescence alters the microbiota and improves mental health, and the molecular basis for multidrug efflux by an anaerobic-associated resistance-nodulation-cell division transporter.

TWiM explains how S. aureus pathogenicity is a dynamic, niche-specific choreography that constantly recalibrates in response to the host microenvironment, and short chain fatty acids produced by commensal microbiota reduces its competitive fitness.

TWiM explains a biological mechanism that links sulfur and iron cycling in anoxic environments, and "swashing," a form of surface movement in which bacteria migrate without active propulsion.
