Figure 2.11: (A) Scanning electron micrograph from a soldier, showing the abundance of bacterial rods and filamentous actinomycetes in close association with the wall of the paunch, covering almost every available surface of the gut epithelium (GE). (B) This micrograph from the paunch of a worker termite shows the same densely packed community of filamentous actinomycetes and rod-shaped bacteria, showing no distinguishable differences in the bacterial morphologies of the hindgut community compared with the soldier sample. Bars = 1μm.
