The occurrence of small (diameter 0.125 micrometers) and large (diameter 0.27 micrometers) treponemal species on expanded polytetrafluoroethylene membranes were demonstrated in vivo. In the apical part of the expanded polytetrafluoroethylene membrane only the smaller treponemes were colonizing, while in other parts a mixed population of different bacterial species including large treponemes was seen. Only the smaller treponemes were able to form spherical bodies in the occlusive part of the membrane. All morphological characteristics of spherical bodies such as common outer sheath, randomly distributed axial flagella, sheathless protoplasmic cylinders and central bodies could be differentiated. Possible causes for the formation of spherical bodies are discussed.
