The entry of a symbiont into the cytoplasm of a host cell, following fusion with the outer membrane, via permeabilization of the plasma (inner) membrane. This process mediates the entry of some non-enveloped viruses into prokaryotic cells. In the case of some double stranded RNA viruses of prokaryotes this occurs via interaction of a membrane-interacting component of the capsid, leading to depolarization and permeabilization of the plasma membrane.
