Is it anything Hfq-like (RNA chaperone)? Or similar to CsrA (global translation modulator)? We don't know yet. But as it stands, Bacteroidota RRM proteins appear as excellent candidates to map post-transcriptional networks in gut microbiota species. nature.com/articles/s41467-0…

We are all living in a bubble that deprives us of experiences needed to understand the true magnitude of the threat posed by the rise of multi-drug resistant infections. It would be wise to allocate resources that match the severity of the threat.

Please mark your calendars for the 8th Conference on Regulating with RNA in Bacteria and Archaea! The meeting will be held September 1 - 4, 2025, at the Strasbourg Convention Centre, Strasbourg, France 🇫🇷.
We are very excited and hope to see as many of you as possible!

We determined gene essentiality in 13 Enterobacteriaceae including E. coli, Salmonella and Klebsiella strains, and find ~1/3 of the essential genome is variable -- but! there's no evidence for genus-specific essential genes, implying rapid turnover journals.asm.org/doi/10.1128…
Thanks to our friends in Dublin for involving us. (-AW)

Last month, Gianluca Prezza (@prezzag) from the lab very successfully defended his PhD. 🎓Congratulations, Gianluca!!!
While we will sorely miss you, we wish you the best of luck for your future endeavors with @ProfTomEllis. (-AW)

Happy to share the results of last 5 years' work in #Klebsiella. By performing iRIL-seq in hypervirulent K. pneumoniae (HvKP ATCC 43816), we discover that ArcZ is a core sRNA inhibitor of capsule & virulence, and that its target gene mlaA is a key virulence factor of hvKP in mice

@lab_rudel introduces the basic concept of @CRC_DECIDE at #DGHMVAAM2024 after two great keynotes by @AndreasPeschel1 and Mathias Hornef: 3 key decisions determine outcome of human infection!

If you ever wondered why your favorite enteric bacterium does not grow well on a particular carbon source, despite carrying all the genes required for uptake & catabolism, this thread is for you ‼️ @PLOSGenetics

Very excited to finally see our study of global RNA stability in Salmonella out today in
@PNASnews, where we use Bayesian statistical modeling to show bacterial transcripts have subminute half-lives, far shorter than previously thought. pnas.org/doi/10.1073/pnas.23… 1/n

Over the moon that the DFG is establishing a priority programme to elucidate gene functions in the human gut microbiome. I am delighted to be coordinating this programme with @TypasLab, @JoergLab and @baerboletta. Exciting science to come!

1/5: Molecular intricacies of gut bacteria! 🧬 Our study in @NatureMicrobiol , with colleagues from @Helmholtz_HIRI, @DeutschbauerLab , & @LBarquist groups, unveils B. thetaiotaomicron's transcriptional landscape across 15 gut conditions. nature.com/articles/s41564-0…
4/5: What's MasB up to? 🤔 Using MS2 affinity purification and RNA-seq, we identify MasB's target and explore its impact on bacterial phenotypes. #MasB #GeneRegulation
5/5: Sharing our discoveries with the world! 🌍 Our data, now publicly accessible via Theta-Base (micromix.helmholtz-hiri.de/b…), serve as a valuable resource for the microbiome research community, fueling further exploration into the fascinating world of gut bacteria.
