| Thermofilum |
| Morphology | Thermofilum |
| CELLULAR |
| Staining | Gram-negative |
| Morphology | Thin rods of 0.15-0.35 um in diameter and 1 to > 100 um in length with terminal pili. In contrast to Thermoproteus, only rarely branched or with sharp bends; often with terminal spherical protrusions on both ends; sometimes with swollen sections; ghosts become spiral shaped. |
