Our paper on how a conveyor belt-associated protein of T9SS-driven gliding bacteria acts as a molecular switch, reversing T9SS rotation to fine-tune movement - like a smart conveyor or biological snowmobile adapting to changing terrain is out now in @mbio.bsky.social journals.asm.org/doi/10.1128/...

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 ...

My PhD student, Emma Henderson, received the Howard C. Berg Award for an outstanding talk on motility by a young investigator at the BLAST meeting #proudpi #blastmeeting2025 @asuSOLS @ASUBiodesign

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.

Crazy stuff in PNAS

dental plaque bacterium 𝘊𝘰𝘳𝘺𝘯𝘦𝘣𝘢𝘤𝘵𝘦𝘳𝘪𝘶𝘮 𝘮𝘢𝘵𝘳𝘶𝘤𝘩𝘰𝘵𝘪𝘪 can divide into an unprecedented 14 daughter cells at once—then each daughter cell starts growing immediately in a rare process called multiple fission, achieving 0.5 mm per day of expansion

These mouth bacteria use a new type of cell division to make 14 cells at once

The newfound strategy seen in C. matruchotii might help oral bacteria recover lost territory after each eviction by toothbrushing.
