Figure 7 Bacteria associated with hindgut cuticle in the papillate region of one specimen. A bacteria are visible near or at the cuticle (C) surface. Bacterial cells are connected to each other with thin filamentous structures (arrow) B bacteria are connected to the fuzzy layer of epicuticle (arrow) by thin filamentous structures (arrowheads).
