Extraordinary pictures show what a common antibiotic does to E. coli The top image shows an untreated E.coli bacterium; the bottom shows a bacterium after 90 minutes of being exposed to the antibiotic polymyxin B Carolina Borrelli, Edward Douglas et al./Nature Microbiology The way antibiotics…

How Bacteria Trick Themselves Into Suicide by Antibiotic Nobody expected the bacteria to commit suicide. But that is essentially what happens when polymyxin antibiotics attack, according to stunning new microscopy images that reveal how these last-resort drugs actually work after 80 years of…

High-resolution imaging shows that polymyxin antibiotics disrupt the protective outer layer of active E. coli cells, but are ineffective against dormant bacteria, highlighting challenges in treating persistent infections.

Now published! www.nature.com/articles/s41... Very nice collaboration with Hoogenboom ( @ucl.ac.uk ) and Bonev ( @uniofnottingham.bsky.social ) labs.

Energized into session 2: How do antibiotics kill bacteria? @ejadouglas.bsky.social @imperialcollegeldn.bsky.social  is casting light onto the mode of action of polymyxin. #LINEsymposium2025
