Figure 3

Electron micrographs demonstrating internalization of A. baumannii in epithelial cells. NCI-H292 cells were infected with A. baumannii 05KA103 at an MOI of 100 for 5 h. (A and B) SEM images showing interaction of A. baumannii with NCI-H292 cells. The cell membrane was extended to and wrapped around A. baumannii (arrow). Bar represents 2 μm. (C to E) TEM images. (C) A. baumannii loosely anchored to the cell surface (arrow) and small protrusion from the cell was appeared (arrow head). (D) The cell membrane was fused after the bacterial internalization (arrow). (E) Intracellular bacteria were surrounded by a membrane-bound vacuole (arrow head). Bar represents 1 μm.
