Figure 5. Localization of major bacterial taxa in the hindgut of an N. vespilloides adult female by fluorescence in situ hybridization.

Bacteria were stained with the general bacterial probe EUB338-Cy5 (green) and taxon-specific Cy3-labelled oligonucleotide probes (red). Nuclei were counterstained with 4,6-diamidino-2-phenylindole (DAPI; blue). (a) Vagococcus, (b) Tissierella, (c) Xanthomonadaceae, (d) Morganella, (e) Providencia and (f) Proteus. Scale bar, 100 μm.
