The phage kills the bacteria by hijacking it's transcription and translational machineries. 

The research identifies a specific bacterial gene sequence that normally gets transcribed and translated into a short peptide. After phage infection, they discover a phage-derived sequence replacing this bacterial sequence, leading to a different amino acid sequence.
