I'm out! Thanks for all those who have followed posts on JB and our lab research. Please find me at BlueSky
@geiselbiofilm.bsky.social
New in JB: Roberge & Burrows review the role of the PilB ATPase and other factors in the assembly of type IV pili.

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. asm.social/2gA
ALT TfpY expression promotes type IV pilus assembly and function. (A) Type IV pilin operon in P. aeruginosa PA14.
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.

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.

Know an outstanding lecturer? Nominate them for the ASM Distinguished Lecturer (ASMDL) roster, a group of accomplished scientists who deliver lectures & participate in career development & mentoring activities at ASM Branch meetings. Submit by Jan. 28! asm.social/2g5
ALT Audience at a lecture.
New in JB: Brezovská, Krásný et al. show that a σA-MoaB2 interaction modulates gene expression in. M smegmatis - and they solve the structure of MoaB2, too.

@ASMicrobiology @JBacteriology
Pls share: Penn State Berks, a college of Penn State University in suburban Reading, has a Tenure-track appointment in biology with a focus in prokaryotic microbiology starting August 2025. A Ph.D. in microbiology or a related field is required.

A new direction for research in the lab around carbon sequestration!

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: asm.social/2fM
ALT Effects of shaking and standing growth on intracellular heme and extracellular porphyrin in mycobacteria. (A) Intracellular heme arbitrary fluorescence units/optical density (AFU/OD) normalized to shaking in Mabs in standing conditions (stand) vs shaking (shake) at 37°C in Sauton’s media. (B) Extracellular porphyrin fluorescence (AFU 654 nm) normalized to OD in Mabs in standing conditions vs shaki
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.

Hi all: I will be X-iting this feed soon and moving to BlueSky: Find me at @geiselbiofilm for all things JB, ASM journals and O'Toole lab and Dartmouth microbiology related posts. I'll keep you posted.
