Lysis induced by phage proteins produced within bacteria during phage infection.
Lysis from within is the normal lysis observed at the end of lytic phage latent periods. See, by contrast, lysis from without.
Lysis from within occurs by a variety of mechanism all of which ultimately entail disruption of the bacterial cell wall, at least in those bacteria that possess cell walls. The lysis process is required to allow translocation of phage progeny virions found within infected bacteria out into the extracellular environment.
