  "summary": "Virally-encoded VIPR systems are thought to use guide RNA-directed proteins to silence competing mobile genetic elements, including bacteriophage satellites. However, whether and how VIPR systems affect viral infection outcomes is unknown. We show here that in Escherichia coli, VIPR arms an infecting phage against competition from a resident phage satellite. The E. coli VIPR's noncontiguous…",
