Copyright © 2010 Pearson Education, Inc. Figure 4.10a Axial Filaments Also called endoflagella or periplasmic flagella In spirochetes only The spirochetes are a … unique group of bacteria. This phylum contains not only many medically important species such as Treponema pallidum and Borrelia burgdorferi but others live inside arthropods such as termites and some that are free-living and reside in soil and water. Individual AF can be anchored at one end or the other of a cell. Rotation causes the cell to move.
