WebMany bacterial pathogens can invade non-phagocytic cells and survive within a membrane-bound vacuole. However, few pathogens are able to escape the vacuoles and proliferate … WebActin comet tails are a result of rapid host actin polymerization beneath bacteria that serves to the propel the bacteria within the host. The actin polymerization is triggered by the surface proteins of certain bacteria like Listeria monocytogenes. Once bacteria gain entry into the cytosol, the endocytic vesicle that contained them is lysed.
