Which term is defined as the science dealing with bacteria?

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

Answer: (A)

The term for the science that studies bacteria is bacteriology. Bacteriology focuses on understanding bacteria—their structure, classification, growth, and how they cause disease—so it’s the field that explains everything about bacteria itself. The other terms refer to different things: cilia are hairlike structures on cells, bacilli describe a rod-shaped form that some bacteria take, and bloodborne pathogens are infectious organisms found in blood that healthcare workers must protect against.
