What is the science dealing with the study of bacteria?

• A. Bacteriology
• B. Cilia
• C. Bacilli
• D. Bloodborne pathogens

Answer: (A)

Bacteriology is the science focused on studying bacteria. This field covers what bacteria are, how they grow and reproduce, their roles in disease, and how we can detect and control them—important ideas for preventing infections in practice. Understanding bacteriology helps explain why certain disinfection and sterilization methods work, and why proper hand hygiene is crucial.

The other terms describe something different: cilia are tiny hair-like structures on cells that help move fluids; bacilli are rod-shaped bacteria, a form of bacteria, not the science itself; bloodborne pathogens are infectious agents found in blood, not a study of bacteria as a discipline.
