Formations of F. alocis in periodontal tissue. FISH on a biopsy gained during periodontal surgery using the probes EUB 338-Cy5 (magenta) and FIAL-Cy3 (bright orange) along with DAPI staining (blue). EUB 338 visualizes the entire bacterial community, while FIAL detects only F. alocis. DAPI stains both host cell nuclei and bacteria. High magnifications depict F. alocis in different parts of the biopsy. (a): F. alocis forms tree-like structures among coccoid and fusiform bacteria and autofluorescent erythrocytes. (b) shows F. alocis forming palisades with fusiform bacteria around large rodshaped eubacterial organisms. (c) shows F. alocis being part of concentrical bacterial aggregations resembling those detected in GAP carriers.
