FISH micrographs of aposymbiotic morph grown under sulfidic conditions for seven days, stained with DAPI (a,e) (n macronuclei of host cells), labelled with EUBmix and Arch915 probes (b,f), and symbiont-specific probe (c,g), and overlay (d,h) arrows points to microbes other than symbionts (e,f). Symbiotic morph grown under sulfidic conditions for seven days stained with DAPI (i)(n macronuclei of host cells), labelled with EUBmix and Arch915 probes (j), and symbiont-specific probe (k) and overlay (l); arrows point to symbionts. Note that all micrographs are the same magnification.
