Which of the following describes the shape of spirilla bacteria?

• A. Rod-shaped
• B. Spherical
• C. Spiral-shaped
• D. Rectangular

Answer: (C)

Spirilla bacteria are specifically characterized by their spiral shape, which is distinct from other bacterial shapes. This type of morphology often allows spirilla to have greater motility compared to rod-shaped or spherical bacteria, as their corkscrew motion can help them navigate through liquid environments more efficiently. The spiral formation is a key feature in identifying these bacteria under a microscope, and it plays a significant role in their biological functions, including locomotion and colonization. Understanding the shape of spirilla is essential in microbiology as it aids in the classification and study of these organisms.
