Working on biofilms!

TfpY is a conserved accessory protein found in type IV pili (T4P)-expressing bacteria. While T4P are often phage receptors, research in #JBacteriology suggests TfpY does not mediate phage defense, but instead facilitates efficient pilus assembly/function. https://t.co/kV6VofQepx

New in JB: Romanov and O'Connor will teach you about the history of Legionella, and its tremendous role as a tool to understand host biology.

My last week on X. Please find me at @GeiselBiofilm on BlueSky

[George O'Toole (he/him/his) @GeiselBiofilm]

New in JB: Garretto, Woods et al. examine 2,248 clinical E. faecium isolates and show that Bacteriocin 43 (bac43) is highly conserved and increasing in prevalence, which has implications for infections/spread by this pathogen.

JB Editor's Choice: Ramírez-Guadiana, Rudner et al. perform a genetic screen to identify spore germination genes. Their data support a model whereby GerY, GerT, and the GerP play a role in the transit of nutrients across the spore coat.

Mycobacterium abscessus (Mabs) is often found in the cystic fibrosis (CF) lung, where it forms biofilms. Exogenous heme alters Mabs biofilms by preventing formation of a submerged film and promoting the growth of unattached aggregates. @JournalSpectrum: https://t.co/4ivLDvGUGA

Just published a new paper with our collaborator here at Dartmouth - Mukul Sharma. This project leverages disciplines from micro to earth sciences to oceanography to explore a new mechanism of carbon sequestration.
