Distinct motors, shared mechanics: unifying principles of microbial gliding | Journal of Bacteriology
Gliding motility is a widespread form of microbial locomotion traditionally defined as smooth movement of a cell along an external surface, enabling active translocation that is distinct from diffusiv...

A molecular conveyor belt-associated protein controls the rotational direction of the bacterial type 9 secretion system | mBio
The type 9 secretion system (T9SS) is fundamental to bacterial gliding motility, pathogenesis, and surface colonization. Our findings reveal that the C-terminal region of the conveyor belt-associated ...

Motile bacterial zorbs demonstrate one of the most fascinating collective migration strategies I have ever encountered. Our lab's postdoc, Jitendra Gosai, gave an excellent talk on the sensory control of zorbs at the BLAST conference.
