Scientists find the “Achilles’ heel” of deadly gut bacteria

Scientists have identified a key weakness in deadly gut bacteria like E. coli and Shigella, which use specific enzymes to break through the gut's protective mucus layer. This breakthrough could pave the way for a universal vaccine to fend off multiple major diarrheal infections. The discovery is significant because it offers a potential single solution to prevent these illnesses, which are a major global health concern, especially in regions with limited medical access. The implications are huge for reducing the burden of diarrheal diseases worldwide.
