Imago of stage W3. Overview (A) and detailed images of different optical sections (B - E) of the midgut of another worker several months of age (W3) by confocal laser scanning microscopy (for further information regarding the composition of the figure see legend of Fig. 1). The number of bacteriocytes is strongly reduced as compared to the worker (W3) shown in Fig. 9. Bacteria present in other cell types than bacteriocytes can be observed (e.g. white arrow in figure part C). Green label: The Blochmannia specific probe Bfl172-FITC; red label: SYTO Orange 83. The scale bars correspond to 220 μM (A) and 35 μM (B - E), respectively.
