Amidst several ongoing innovations to look for solutions, Scientists from Switzerland utilizing new high-resolution microscopic images, showed that Polymyxins, one of the mysterious last-resort antibiotics, crystallize the cell membranes of bacteria. Scientists utilized a powerful tool called atomic force microscopy (AFM) along with structural biology and biochemistry assays to study how polymyxin antibiotics interact with lipopolysaccharide (LPS) in bacterial membranes.   They discovered that polymyxins arrange LPS into hexagonal assemblies to form crystalline structures. After almost a hundred years of its use, scientists provided evidence to suggest that the formation of rigid LPS–polymyxin crystals and subsequent membrane disruption is the mechanism of polymyxin action. This discovery could provide a benchmark for optimization and de novo design of LPS-targeting antimicrobials, with hopes to tackle the AMR problem more efficiently. While these are promising developments for the future, as of now, diagnosing infections promptly using kits like [Acutis Reveal™](https://info.acutis.com/biopharma-partners-infectious-disease), and treating them appropriately at first is the only measure to curb the burden of AMR.   [Read the full article here](https://www.nature.com/articles/s41467-022-33838-0) ![avatar](https://blog.acutis.com/hs-fs/hubfs/Sales%20materials%202023/Brand/logo-acutis%20HD-2022-1.png?width=290&name=logo-acutis%20HD-2022-1.png) #### [Acutis](https://blog.acutis.com/author/acutis) Our team of scientific experts is here to help you understand the trends in infectious disease, clinical toxicology, and Biosciences that are happening in the world.
