What is the role of the axial filament in spirochetes?

Where is the axial filament located in spirochetes?

How does the axial filament in spirochetes differ from typical bacterial flagella?

Which of the following best describes the structure of the axial filament in spirochetes?

Spirochetes use an axial filament to be motile. This is similar to a cellular flagella but this structure wraps through the whole cell. It is located between the periplasmic space between the inner and outer membranes of the cell.
