Fig. 8. Thin section through a U937 cell with a phagosome containing a dotA mutant. This U937 cell was infected for 45 minutes prior to fixation. The phagosomal membrane does not have attached ER vesicles. Furthermore, the thickness of the phagosomal membrane remains as thick as the plasma membrane (70 Å thick (b)). As in Fig. 7, phagosomes containing dotA mutants fuse with lysosomes.
