Scientists have uncovered a shared vulnerability in deadly gut bacteria like E. coli and Shigella—specific enzymes they use to breach intestinal mucus. Targeting this common mechanism could lead to a single vaccine protecting against multiple strains, offering hope for millions affected yearly, especially children. By studying natural antibodies and using advanced imaging, researchers pinpointed how these antibodies block the enzymes, revealing a precise immune target. This breakthrough builds on past findings and could revolutionize prevention, reducing antibiotic use and tackling…
