Pleased to reveal that our team has been selected for 2 oral presentations at #ESCMID
@escmid.bsky.social Global in Munich! Both lines of research spearheaded by the fabulous @microberamon.bsky.social. #UTI isn’t just a serious healthcare problem - the science is an intriguing puzzle! #IDSky #UTISky

Gut-relevant short-chain fatty acids modulate host-pathogen dynamics of uropathogenic Escherichia coli at the colonic epithelial interface https://www.biorxiv.org/content/10.64898/2026.01.19.700340v1

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/...

Congratulations!!!!!! 🥳🥳 in my reading list!!! 🙏🏼

Happy birthday Jenny!!! 🥳

Congratulations @tosinorababa.bsky.social 🥳🥳🥳

Effect of human urinary microenvironment and fluid flow on antibiotic and phage therapy efficacy against uropathogenic Escherichia coli Urinary tract infections (UTI) remain a major global health burden, with high recurrence despite antibiotic treatment. The escalating prevalence of antimicrobial resistance further compromises therape...

Very pleased to plug our latest preprint, lead author @microberamon.bsky.social - fantastic collaboration with labs of Dario Carugo (Oxford) and Martha Clokie (Leicester) https:// - and others #UTISKy #UTI #IDSky #MicroSky www.biorxiv.org/content/10.1101/2025.11.12.688052v1 more below👇🧵

PhD opportunity in my lab: exploring how commensals and pathogens build biofilm communities on endotracheal (ventilator) tubes. Microbial ecology, medical microbiology and fancy imaging! Co-supervised with the fabulous Saskia Bakker and Jeremy Webb warwick.ac.uk/fac/cross_fa... #MicroSky

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

Same chemistry, different architecture → different mechanisms.

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.

So in denial that I cannot open my eyes 🥹🤣

🥹 not going far!!!! 💪

I guess we can call this Cellfie 😂

Interesting cross-disciplinary technician position in our lab! You can learn all things microbiology and a beautiful organoid culture system while sitting in the heart of London @ucl.ac.uk ! Perfect for freshly graduated students. Apply! #UTISky #microbiology

Really cool exhibition at the London Design Biennale 2025. Microbiome Modulators as bioactive ceramics and probiotic interventions embedded in ceramic elements 🦠

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 💇‍♂️😂

Thank you!!! 🙂

We need better tools to mimic the host-microenvironment and bacterial adaptations to recapitule bacterial infections in the human body. Super proud of the team @victoriachu.bsky.social @nickyuen.bsky.social @murraybeno.bsky.social @anniejoseph.bsky.social @jennyrohn.bsky.social

Effect of host microenvironment and bacterial lifestyles on antimicrobial sensitivity and implications for susceptibility testing - npj Antimicrobials and Resistance npj Antimicrobials and Resistance - Effect of host microenvironment and bacterial lifestyles on antimicrobial sensitivity and implications for susceptibility testing

Absolutely thrilled this is out🥳Our review explores why antibiotics often fail even when bacteria is susceptible in the lab. From phenotypic resilience and biofilm formation to host microenvironment, we dive into many factors behind these discrepancies

Absolutely thrilled to present our latest review, where we discuss how host microenvironment and bacterial subversion strategies can undermine traditional antimicrobial sensitivity testing, and whether better models may one day get us "beyond the MIC" #IDSKy
