@archaeabio.bsky.social can maybe help here?

The latest and most detailed review on a fundamental biochemical pathway: #glycolysis #microbiology #biochemistry onlinelibrary.wiley.com/doi/full/10....

In a manuscript on BioRxiv, we describe experiments exploring the culturome of the gut of adults with CF and in health, revealing an interesting redistribution of the microbes in the lumen vs. mucosa. The study is led by Sarvesh Surve a PhD student in my lab. www.biorxiv.org/content/10.1...

When life gives you lab electrical shutdowns for maintenance … you make the most of the first bits of east coast snow!

Very excited to share a big part of my dissertation work with the Deutschbauer lab at LBNL and @ucberkeleyofficial.bsky.social! BarTn7: A method for bacterial lineage tracking at sub-species resolution in population, ecological, and evolutionary experiments. www.biorxiv.org/content/10.1...

Excited to share new work from Sarvesh Surve examining the gut microbiota of adults with CF using colonoscopy samples and a culturomics approach. We note continued depletion of Bacteroidota (which we noted in kids) & enrichment of aerobes in the mucosa of pwCF. pubmed.ncbi.nlm.nih.gov/41256617/

Clone-FISH paper out: Manuscript/resource alert #microsky 🦠 We present a collection of 30 E. coli (CloneFISH) cultures, each carrying a plasmid for the heterologous expression of a (near) full-length 16S rRNA gene from one of 30 lineages of archaea, including 17 yet uncultured ones.

Prevotella is the clear favorite of the 4-member cookie community (not like I’m surprised) @bassamhafi.bsky.social @fabricejpierre.bsky.social

Congratulations to Bassam el Hafi, who successfully defended his PhD thesis yesterday! He did a terrific job! Bassam connected microbial interactions to the complexity of human communication. Thanks also to Sarah Clark of the Anschutz School of Medicine who served at Bassam's outside examiner.

New in JB: A minireview from my team, led by a recently graduated PhD student Kaitlyn Barrack, compares the microbiota and physiology of the CF gut with features of the gut in inflammatory bowel disease - there are many similarities! journals.asm.org/doi/10.1128/... @asm.org #JBacteriology

We're thrilled to announce SeqHub, an AI-enabled platform for biological sequence analysis. SeqHub brings together sequence search, genome annotation, and data sharing in one place.

Excited to be part of this collaboration with the Burrows lab exploring twitching and surface surface sensing by P. aeruginosa. This work further delineates a role for the T4P motor proteins and pili for surface sensing. journals.asm.org/doi/10.1128/... @asm.org

Earlier this month, we proudly welcomed the newest cohort of Damon Runyon Fellows! These 16 brilliant postdocs will receive four years of independent funding to advance their investigation of causes, treatments, and prevention strategies for all types of cancer. Read more: https://bit.ly/4nc25Hq

In #mBio, dive into story behind the 1989 discovery of Helicobacter pylori CagA, the first tumorigenic bacterial protein. This article recounts the early steps in the investigative process and relates some of the unexpected discoveries that ensued. asm.social/2C1

Happy to finally see this out! Bassam El Halfi (@bassamhafi.bsky.social - my first rotation student when I started my post-doc in @geiselbiofilm.bsky.social) did an amazing job investigating mechanisms of interspecies metabolic interactions. Check it out! #microsky journals.asm.org/doi/10.1128/...

Excited to share our latest work, driven by my recently graduated PhD student Kaitlyn Barrack, exploring the mechanisms of bacterial dysbiosis in the CF gut - including a role for a colorectal cancer-associated genotoxin in this competition. www.biorxiv.org/content/10.1... @kbarrack.bsky.social

Excited about our most recent collaboration with the Wong lab, lead by William Schmidt, describing a T4P and CdrA-mediated mechanism of sensing surface EPS. Fun stuff and great work William and team. www.nature.com/articles/s41...

The latest and greatest from an amazing team of authors. See what you think: A Comprehensive Framework for Assessing Terrestrial Analogue Field Sites for Ocean Worlds - Stern - 2025 - Journal of Geophysical Research: Planets - Wiley Online Library agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Incredibly honored to be a Damon Runyon Fellow! @damonrunyon.org

Our newest manuscript on the gut-lung axis in CF, lead by Rebecca Valls, explores sex and intestinal regional differences in response to Bacteroides. Check it out! www.biorxiv.org/content/10.1...

We had the O'Toole Lab Reunion on Sat here at Dartmouth, celebrating 26 amazing years - science is all about the people, and I have been fortunate to have a great bunch of folks in the lab over the years! And THANKS to all the lab members who did all the organizing!

Microbes rarely exist alone; instead, they live in dynamic communities. In #IAIJournal, researchers discuss the interplay between the host environment & microbiome metabolism & the impacts on disease progression in host-associated polymicrobial communities. asm.social/2yf

Excited about our most recent paper lead by Kaitlyn Barrack, a minireview in JB comparing the CF and IBD guts - from microbiomes to physiologies. There are many similarities... journals.asm.org/doi/10.1128/... @asm.org #JBacteriology @kbarrack.bsky.social
