Researchers have revealed how polymyxins, crucial last-resort antibiotics, break down bacterial armor by forcing cells to overproduce and shed it. Astonishingly, the drugs only kill bacteria when they ...

Scientists have released new images showing, in incredible detail, antibiotics defeating disease-causing bacteria by piercing the microbes' membranes and infiltrating their innards. The antibiotics, ...

Our bodies are a constant battlefield between pathogens and our immune system. But beyond this battle, there’s a larger war being fought between humans and drug-resistant bacteria. When antibiotics ...

Composite image of E. coli exposed to the polymyxin antibiotic – the images show the changes to the outer layer of armour over time. From left to right: bacterium untreated by the antibiotic; ...

The findings, published in the journal Nature Microbiology, could lead to new treatments for bacterial infections – especially urgent since drug-resistant infections already kill more than a million ...

Physicians have relied on a class of antibiotics called polymyxins to fight potentially life-threatening Gram-negative bacterial infections for more than 80 years. These drugs are typically reserved ...

(Nanowerk News) A team led by UCL (University College London) and Imperial College London researchers has shown for the first time how life-saving antibiotics called polymyxins pierce the armour of ...
