| Morphology | Spirochaetacae |
| CELLULAR |
| Staining | Gram negative |
| Morphology | Helical cells, 0.1-3.0 um in diameter and 5-250 um in length. Ends of cells usually not hooked |
| Motility | motile by periplasmic flagella |
| Specialized structures | Individual periplasmic flagella extend along most of the length of the cell. Thus, flagella inserted near opposite poles of the cell overlap and are in close apposition to one another in the central region of the cell |
