Candida albicans steals magnesium and Pseudomonas aeruginosa unleashes resistance - Nature Reviews Microbiology This study uncovers how Pseudomonas aeruginosa acquires colistin resistance in magnesium-depleted environments created by Candida albicans by accumulating unique mutations in the lipid A biosynthetic ...

Regulators of gut motility revealed by a gnotobiotic model of diet-microbiome interactions related to travel - PubMed To understand how different diets, the consumers' gut microbiota, and the enteric nervous system (ENS) interact to regulate gut motility, we developed a gnotobiotic mouse model that mimics short-term dietary changes that happen when humans are traveling to places with different culinary traditions. …

Does anyone know if carmine red affects gut microbiota composition in mice? This paper says it does not but doesn’t seem to actually show the data and the only other papers we found cite it to support the claim 🫠. pubmed.ncbi.nlm.nih.gov/26406373/

Super cool, looking forward to reading this!

Here’s the latest preprint from my work on evolved resistance to Type VI Secretion system (T6SS) weaponry, funded by a @wellcometrust.bsky.social Sir Henry Wellcome Fellowship. So happy to see this out!

Two weeks left before the deadline! My colleague extraordinaire @whelanfj.bsky.social is looking for a post-doc to work on P. aeruginosa genomics in the context CF lung infections. This is a collaborative project between my lab, hers and @jpcote.bsky.social's lab. The data is ready to be analyzed!!

So cool!

Wow that is spectacular!

Magnesium depletion by Candida albicans unleashes two unusual modes of colistin resistance in Pseudomonas aeruginosa with different fitness costs Bacterial resistance to the vital last-resort antibiotic colistin is an increasing challenge. This study shows that magnesium sequestration by C. albicans enables P. aeruginosa to evolve much higher l...

Our story on the evolution of colistin resistance is just out on @plosbiology.org (journals.plos.org/plosbiology/... Evolution doesn’t happen in isolation. We show that competing fungi can rewire the evolutionary trajectory of colistin resistance in P. aeruginosa. Great teamwork with the Ernst lab

In remembrance of Peer Bork  | EMBL EMBL and its community are deeply saddened by the death of Peer Bork, the organisation’s Interim Director General.

very sad news. Peer Bork was one of the leaders of our field, a wonderful scientist, and he's much too young to be gone. www.embl.org/news/embl-an...

Here, we find that many Genomic islands have origins of transfer (oriT) mobilisable by conjugation, incl. known Pathogenicity & defense islands. iOriT use only an oriT for transfer by hitching on conjugative elements: they make abundant, diverse, ancient families of mobile genetic elements. See🧵

Proud to announce SimPhyNI, a new tool for bacterial GWAS with higher precision and scalability than existing tools. Try it out and let us know what you think!!

Gene-specific selective sweeps are pervasive across human gut microbiomes - Nature Development and application of the integrated linkage disequilibrium score (iLDS) reveals both selective pressures impacting the human gut microbiome and the mechanisms by which gut bacteria adapt to ...

Grateful to share our paper on gene-specific selective sweeps in human gut microbiomes, now out in Nature! It has been a joy to work with @rwolff.bsky.social, whose insights and hard work made this possible.

Bacterial conjugation can restructure biofilms and increase their resilience while constraining host cell dispersal Winans et al. show how plasmid transfer can reorganize bacterial communities into dense aggregates, conferring antibiotic and phage tolerance to otherwise sensitive host cells. Conjugation-dependent a...

I think some folks might be happy to see this. NIGMS MIRA R35 for EI/NI has been published. PAR-26-121 files.simpler.grants.gov/opportunitie...

I wrote my PO who said that they are hoping it will come out soon but this has to now be reviewed at the HHS level and so they have no more info. Said that since it has to be posted 60d ahead of first deadline, the Jan deadline may have to be postponed.
Mild panic is ensuing.....

😞

I’m curious if anyone has heard anything about the status of the NIGMS R35 MIRA, currently there is no next submission deadline for established investigators and we have now passed the forecasted new announcement date

Poster deadline for the Keystone Microbiome Meeting in Banff is December 30th www.keystonesymposia.org/conferences/...

Will be a great meeting focused on human microbiomes, spanning basic, mechanistic, and applied. Organized by myself, @amibhatt.bsky.social , and Harry Sokol. Join us!
