Bacteria Reveal a Hidden Viral Alarm System, Opening New Paths for Phage Therapy and Biotechnology
Scientists have identified how certain bacterial immune systems detect infection by sensing a viral protease, a mechanism that allows bacteria to trigger a defensive response when phages invade. The finding, reported in Nature, clarifies a long-standing question in microbial biology and could help shape future phage-based antibiotics, synthetic biology tools, and precision antimicrobial strategies.
