Phage-induced lysis of a bacterial cell resulting, in most instances, in liberation of number of phage progeny virions.
The idea of a phage burst gives rise to that of "burst size".
This is the definition from Adams (1959), p. 439: "Yield of phage liberated by spontaneous lysis of an infected bacterium. This may be measured directly for isolated bacteria in single burst experiments, or as an average burst size in one-step growth experiments. Also the act of liberation."
