New preprint: "A branching cell-fate decision in biofilm dispersal enables long-term surface persistence." When V. cholerae biofilms disperse, it isn’t a uniform exit, rather, an opportunity to bet-hedge. A subpopulation of cells stay behind, primed for biofilm regrowth. doi.org/10.64898/202...

Congratulations to @emmynguyen.bsky.social and our wonderful collaborators. Here we uncover and characterize a periplasm protein that modulates broad physiological changes to V. cholerae by controlling a two component system!

A small periplasmic protein governs broad physiological adaptations in Vibrio cholerae via regulation of the DbfRS two-component system - Nature Communications
A two-component system, DbfRS, regulates biofilm formation in Vibrio cholerae. Here, Nguyen et al. identify a small periplasmic protein that controls the activity of the system’s receptor, and show th...

We determine that additional pathogenic organisms also exhibit multicellular community formation in response to lysis. Given the pervasiveness of lysis in the environment, we propose that lysis sensing is a threat-agnostic mechanism by which bacteria can gauge endangerment. (4/4)

Drew Bridges @bridgesbio.bsky.social · 06/03/2024
We identify the cell lysis signal as an abundant cytoplasmic polyamine, norspermidine, which is detected by an inner-membrane receptor, MbaA, that in turn drives biofilm formation. (3/4)

Drew Bridges @bridgesbio.bsky.social · 06/03/2024
We find that the mechanism underlying this observation is a process we refer to as "lysis sensing"...whereby surviving cells sense a signal released by the death of their kin. (2/4)

Drew Bridges @bridgesbio.bsky.social · 06/03/2024
Our first paper from the lab! We find that upon exposure to lytic phages, the pathogen V. cholerae rapidly lyses, but then recovers, with surviving cells exhibiting robust biofilm formation. www.nature.com/articles/s41... (1/4)

Had a blast writing a commentary #msphere on “Biogeography of a human oral microbiome at the micron scale” by @jmarkwelch.bsky.social et al. The work in this paper made me want to be a microbiologist. I vividly remember an MBL lecture by Gary Borisy on the topic when I was a grad student.
