How do spirochetes and spirilla differ? O Spirochetes have a rigid, corkscrew shape while spirilla are helical and more flexible. O Spirochetes do not have a cell wall but spirilla do. Spirilla have external flagella but spirochetes have axial filaments. O Spirilla are found in chains of cells whereas spirochetes exist as individual cells. O Spirochetes and spirilla are basically the same organisms and the terms can be used interchangeably.

Expert Solution
Step 1
Spiral bacteria, including the spirilla and spirochetes, are a morphological grouping of prokaryotes having helical-shaped cells. Gram-negative, spiral, motile bacteria (3–500 m in length; 1 m = 0.001 mm) are called spirochetes. The genus Spirillum belongs to the Spirillaceae family, which is in the Nitrosomonadales order of the Betaproteobacteria.
