What shape is associated with a spirochete?

• A. Circular
• B. Bends - snake-like
• C. Helical
• D. Linear

Answer: (B)

Spirochetes are distinguished by their unique shape which resembles that of a corkscrew or a snake. This characteristic structure allows them to exhibit a twisting and bending motion, which is crucial for their motility. The snake-like bends enable spirochetes to move through viscous environments, such as mucus, and to invade host tissues effectively. The ability to propel themselves in a way that resembles the undulating motion of a snake is key to their pathogenicity. This motion is achieved through the presence of axial filaments, which are flagella-like structures that wrap around the cell body, allowing for that distinct movement. This makes the association of spirochetes with a snake-like shape the most accurate representation of their morphology.
