TEM images of L. monocytogenes F4244 cells grown in LB with 0.0 (A and B), 0.8 (C and D), or 3.2 g of glucose/liter (E and F) and probed with immunogold-labeled LAP-specific monoclonal antibody (A, C, and E) or with polyclonal antibody (B, D, and F). Arrows indicate the cell surface location of LAP, and the circle indicates patchy distribution.
