FIG. 3.
Fluorescence in situ hybridization of subgingival plaque material from an RPP patient. (a) Microphotograph showing simultaneous hybridization with EUB338FITC (green) and TRE ICy3 (yellow). The eubacterial probe reveals the different morphotypes of subgingival plaque bacteria and the spherical bodies of the treponemes (arrows), as described by Wecke et al. (33). (b) Microphotograph showing hybridization with TRE IFITC (green) and TRE IICy3 (yellow). Note the different morphologies of the treponemes detected with the group-specific probes.
