Added to my reading list!!! 🙏🏼 thanks for sharing 😉

A four-panel figure showing scanning electron micrographs of Pseudomonas biofilm on the surface of pig lung tissue. Aggregates of bacteria sit on top of a network of collagen fibrils, with some bacterial cells penetrating the collagen mesh.

Paper out! We used RNAseq to track changes in P. aeruginosa gene expression over 7 days of #biofilm infection in our #CysticFibrosis lung model. www.microbiologyresearch.org/content/jour... #MicroSky (1/n)

Recurrent and chronic UTIs have a huge impact on patient's quality of life and is an area of research which is often overlooked and understudied. There are massive gaps in our understanding which we can fill to... (1/3)

Four graphs, showing the response of PA14 and an isogenic pel mutant, and PAO1 and an isogenic pel psl double mutant, to meropenem and colistin. There is no difference between the response of mutants and WTs.

During her PhD, Jenny found something unexpected: biofilm-deficient P. aeruginosa mutants were just as tolerant to antibiotics as the WT when grown in our cystic fibrosis lung model. But why? #MicroSky 1/n

Congratulations!!!! 🥳 amazing news!!!

Now, this is officially a problem. MSCA fellowships need to be competitive, but it cannot be a lottery. Time to focus on the core mission of supporting science and ditching all vanity initiatives in the Horizon Europe program. (Looking at ERC super-grants...)

Excited to share our preprint that describes the mechanism of action of an historical infection remedy called Bald’s Eyesalve. In this preprint, we show that Bald’s Eyesalve has multifaceted mechanism of action against both S. aureus and A. baumannii (1/n).

Less than one week to apply to this 2.5 yr PDRA!

If you're passionate about biophysics #AFM #Microscopy applied to bacteria and #antimicrobial research this will be a great opportunity in the beautiful city of Sheffield. 😀

Enterococcus faecalis: an overlooked cell invader | Microbiology and Molecular Biology Reviews SUMMARYEnterococcus faecalis and Enterococcus faecium are human pathobionts that exhibit a dual lifestyle as commensal and pathogenic bacteria. The pathogenic lifestyle is associated with specific conditions involving host susceptibility and intestinal ...

🧵Enterococcus faecalis is not just an extracellular organism. 🧵 A growing body of work shows it can survive + REPLICATE inside host cells, and that intracellular life may seed persistence, dissemination, and reinfection. 1/n #MMBR @asm.org journals.asm.org/doi/10.1128/...

A cartoon showing a Gram-negative bacterium exposed to two variants of a polymer. A triblock structure causes formation of multiple small pores in the outer membrane. A diblock structure causes large pores in both outer and inner membranes, and cell lysis.

Another paper from @microberamon.bsky.social's PhD 🦠 Two structural variants of an AMP-inspired antimicrobial polymer have different effects on P. aeruginosa. One kills with a bang, the other with a whimper pubs.acs.org/doi/10.1021/... #MicroSky @sebperrier.bsky.social @alexiahapeshi.bsky.social

Massive thanks to all the authors, what a ride! Couldn’t have done it without you 💙 @laia-pasquina.bsky.social @friendlymicrobe.bsky.social @alexiahapeshi.bsky.social @sebperrier.bsky.social and the wizard of NR Steve Hall

Assessing the Mechanism of Action of Synthetic Nanoengineered Antimicrobial Polymers against the Bacterial Membrane of Pseudomonas aeruginosa The lack of appropriate antimicrobials to tackle multidrug-resistant Gram-negative bacteria poses an escalating threat to modern medicine. Addressing this urgent issue, we have recently developed synt...

🎉 Super happy to finally share our new paper in ACS Biomacromolecules!
We used AFM & neutron reflectometry to study how two SNAPs (synthetic nanoengineered antimicrobial polymers) disrupt P. aeruginosa membranes.

Proud to present my work at the UK Cellular Microbiology Network Meeting earlier this week. Lots of great feedback and some very interesting talks! Congrats to all the speakers. Well done @microberamon.bsky.social for representing the lab. I like the rainbow title slide 😂 @jennyrohn.bsky.social

A man gesturing at a presentation on a stage.

Great talk about polymicrobial biofilms in #UTI by our fabulous postdoc @microberamon.bsky.social! #UKcellmicro2025 #UTISky

Really excited about this opportunity! I will be sharing part of my postdoc work at Rohn lab @jennyrohn.bsky.social and a new hairstyle 💇‍♂️😂
