TEM micrographs of extracellular bacteria in the midgut glands of P. pruinosus (a, c, d) and O. planum (b, e). a, b Large views showing dense bacterial populations in the lumen of the midgut glands of P. pruinosus (a) and O. planum (b), often in close vicinity to the midgut epithelium (b). The bacteria often form stalk-like protrusions at one cell pole, which is inserted between the microvilli of the epithelium (c–e). mi mitochondrion, mv microvilli. Scale bars: a = 2 µm, b = 1.5 µm, c = 500 nm, d = 200 nm, e = 1 µm.
