Apical end of an uninfected midgut epithelial cell. The cytoplasm contains mitochondria (M), rough endoplasmic reticulum (rER), and, near where microvilli (MV) extend out into the midgut lumen, a reticulate network (RN). Electron opaque material (arrows) was observed around mitochondria and the reticulate network. The zonula continua separating two epithelial cells can be seen on the left (arrowheads). Electron micrograph. Scale bar = 1 μm.
