Which bacteria are spiral-shaped?

Explanation:
Bacteria come in three common shapes, and this item focuses on recognizing spiral forms. Spiral-shaped bacteria are called spirilla. The other options are not spiral: streptococci and staphylococci are spherical (cocci)—they form chains or clusters—while bacilli are rod-shaped. Spirilla are typically rigid, helical bacteria that move with a twisting motion due to their external flagella. Think of spiral = twisting, which helps remember spirilla.
