Basal end of a midgut epithelial cell at 48 hpi. A layer of basal lamina (BL) lies between the midgut cell and a muscle cell (MC). Mitochondria (M) and a bacterium (B) can be seen in the cytoplasm of the midgut cell in between the invaginations of the plasma membrane (arrows). These plasma membrane invaginations appear irregular compared with those in Figures 7 and 8. Electron micrograph. Scale bar = 1 μm.
