This study directly analyzes gut bacterial motility in health and inflammation, finding increased motility in inflamed conditions and diverse swimming behaviors.

This study shows that curved Vibrio cholerae cells swim more efficiently through mucus-like hydrogels than straight mutants, with curvature enhancing chemotaxis by reducing stalls.

The paper establishes a publicly available collection of 340 human gut bacterial strains, including 29 newly described species, and identifies plasmids and megaplasmids within these isolates.
