Congrats to Ann-Sophie Rüttiger who successfully defended her PhD this week! 🎓 She focused on global RNA-binding proteins in Bacteroides—bacteria lacking Hfq, ProQ, CsrA, Khp—culminating in the discovery of a post-transcriptional network governed by RbpB (www.nature.com/articles/s41467-024-55383-8).

Latest preprint from the lab: doi.org/10.1101/2025... In this study lead by @lenaamend.bsky.social from the group, we explore carbon cross-feeding between a gut commensal and an enteropathogen. Can we counter infection by cutting sugar supply to pathogens?

Ablation of polysaccharide breakdown in Bacteroides thetaiotaomicron prevents cross-feeding and growth of Salmonella Typhimurium in the mouse gut https://www.biorxiv.org/content/10.1101/2025.08.08.669261v1

Very honored that our recent study on Bacteroides morphotypes was spotlighted 🔦 in Trends in Microbiology by Eric Martens & Qinnan Yang: www.cell.com/trends/micro....

Our latest: www.cell.com/cell-reports/fulltext/S2211-1247(25)00615-1. Links Bacteroides cell size w/ gene expression. Protocol works even for single cells. 🦠 Shoutout to @elisebor.bsky.social, @emmanuel-saliba.bsky.social, @lbarquist.bsky.social, @jorg-vogel-lab.bsky.social, Till Strowig & KC Huang.

Some say, important sRNAs can be recognized by having their own “sponge” 🧽. Well, here comes InvS: a sponge of PinT (and vice versa). Congrats to @kooshapour.bsky.social and @ginlaca.bsky.social on their great work! doi.org/10.1101/2025...

Honored to have been one of the selected scholarship awardees at the Keystone Symposium on the Human Microbiome in February 2025 in Banff, Canada. I had an amazing time! #KSHumanMicro25 #KSHostMicrobe25 #keystonesymposia

Exciting developments from Banff, Canada, as we celebrate our award recipients at the joint meeting on Human Microbiome and Host-Microbe Co-Evolution in Human Health. Join us in applauding these exceptional scholarship winners! #KSHumanMicro25 #KSHostMicrobe25 #keystonesymposia
