Summary

How do bacteriophages (viruses that parasitize bacteria) escape from their bacterial hosts once they have replicated? In a Perspective, Hatfull discusses new work ( Bernhardt et al.), which reveals that certain bacteriophages are able to block enzymes that synthesize precursors of murein, a crucial component of the bacterial wall. Weaknesses in the bacterial wall due to the murein deficit result in lysis of the bacteria and release of phage progeny.
