What are spiral-shaped bacteria called?

Cocci
Bacilli
Spirilli
Vibrios

The correct answer is: Spirilli

Spiral-shaped bacteria are referred to as spirilli. This classification is part of the broader taxonomy of bacteria based on their shapes. Spirilli are characterized by their elongated, spiral structure, which may vary in tightness and number of turns, contributing to their mobility and distinctive appearance when viewed under a microscope. Cocci are spherical bacteria, while bacilli are rod-shaped. Vibrios, on the other hand, are a specific genus of bacteria that are curved or comma-shaped. While all of these terms relate to the shape of bacteria, spirilli specifically denotes those with a spiral configuration, making it the correct answer. Understanding these classifications is essential for identifying different types of bacteria and comprehending their characteristics, behavior, and relevant clinical implications.
