New in PLOS Pathogens 🎉 How does OM-89 (Uro-Vaxom) protect against recurrent UTIs? 🦠 Our paper: it activates lysosomes in bladder epithelial cells, pushing intracellular E. coli into acidic, protease-active compartments and improving antibiotic killing. 🧵 10.1371/journal.ppat.1014448 #UTISky #UPEC

A new study led by @microberamon.bsky.social from 🇬🇧 @oxengsci.bsky.social, with @ucl.ac.uk and @uniofleicester.bsky.social, shows that #phagetherapy could help to reduce recurrent #infections, which happen when the 🦠 bacteria responsible for #UTI s ‘hide’ in the tissue of the #bladder.

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
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.
