Vesicular exocytosis in prokaryote gram negative bacteria is a third mechanism and latest finding in exocytosis. The periplasm is pinched off as bacterial outer membrane vesicles (OMVs) for translocating microbial biochemical signals into eukaryotic host cellsYashRoy R C (1993) Electron microscope studies of surface pili and vesicles of Salmonella 3,10:r:- organisms.
