Abstract
Phage fd-infected host bacteria revealed three characteristic changes in their envelope. (i) The preferred cleavage plane during freeze-fracturing shifted from the inner to the outer membrane (OM). (ii) The total lipids of the OM of the infected cells increased by 25% without major alterations in the relative concentration of phospholipids. We propose that such an increase would to some extent contribute to the change in the freeze-fracture behavior of the OM; however, additional factors will have to play a role in the apparent fracture resistance of the inner membrane. (iii) Ultrathin sectioning and immunolabeling methods revealed that extrusion of fd phages takes place at membrane adhesion sites of the infected cells.
