FISH image of pingo worm trophosome cross section.
Fluorescence in situ hybridization of bacterial symbionts on a cross section of a pingo worm (sample 1078–13): Epifluorescence images showing host nuclei, stained with DAPI (blue), and bacterial symbionts in red, hybridized with LaSp probes from Duperron et al., 2009. A: entire cross section at the level of the trophosome. B: close up of top right part of cross section shown in A. Note the high densities of bacterial symbionts.
