# Bacteria use diverse receptors to detect core proteins of invading phages

Researchers have discovered that bacteria employ a wide range of pattern recognition receptors to sense conserved proteins from the core proteome of bacteriophages. This finding reveals a universal mechanism by which bacteria detect phage infections, offering new insights into bacterial immunity. Understanding this system could inform the development of phage-based therapies and combat antibiotic resistance.
