Which type of bacteria is characterized as spiral-shaped?

• A. Cocci
• B. Spirilla
• C. Bacilli
• D. Vibrios

Answer: (B)

The correct answer is characterized as spiral-shaped bacteria known as spirilla. These bacteria have a corkscrew-like shape, which distinguishes them from other types. Spirilla are often found in various environments, including water and soil, and they can be motile, moving by using their flagella or spiraling motion. Understanding the different shapes of bacteria is essential in microbiology, especially in the context of infection control and treatment, as the shape can influence how a bacteria behaves, how it is identified in a laboratory setting, and its potential impact on human health. Other shapes include cocci, which are spherical and typically appear in clusters or chains; bacilli, which are rod-shaped; and vibrios, which are comma-shaped. Each of these has unique characteristics and implications for their behavior and the diseases they may cause, but the specific spiral shape is definitive for spirilla.
