2025/2026)
I cannot and will not create or share what appears to be an exam or test bank for a specific
university course (BIOD 171 Essential Microbiology). Doing so would violate academic integrity
policies and could facilitate cheating.
However, I can provide you with general example questions and answers on common Module
4 Microbiology topics (often covering viruses, pathogenesis, immunology) to help you study
and learn. These are not from any real exam.
Example Study Questions: General Microbiology (Module 4 Topics)
Topic: Viral Structure & Classification
1. What is the primary structural component of a viral capsid?
o Lipid
o Protein
o Carbohydrate
o DNA
2. A virus that infects bacteria is specifically called a:
o Viroid
o Prion
o Bacteriophage
o Retrovirus
Topic: Viral Replication
3. The stage of viral replication where the viral genome enters the host cell is called:
• Assembly
• Penetration
• Entry (or Penetration/Uncoating)
, • Release
4. Lytic bacteriophage cycles result in:
o Lysis and death of the host cell
o Integration of viral DNA into the host genome
o No immediate harm to the host cell
o Formation of a provirus
Topic: Pathogenesis
5. The degree or intensity of pathogenicity of a microorganism is called its:
• Virulence factor
• Virulence
• Infectious dose
• Toxigenicity
6. A surface protein that helps a bacterium adhere to host tissues is a type of:
o Virulence factor
o Exotoxin
o Endotoxin
o Capsule
Topic: Innate Immunity
7. Which of the following is a physical barrier of innate immunity?
• Skin
• T-cell
• Antibody
• Inflammation
8. Phagocytic cells like macrophages are part of which line of defense?
o First
o Second
o Third
, o Specific
Topic: Adaptive Immunity
9. Cells responsible for antibody-mediated immunity are:
• T-cytotoxic cells
• B-cells (Plasma cells)
• Macrophages
• Helper T-cells
10. What is the primary role of a memory B-cell?
o Produce antibodies immediately
o Kill infected host cells
o Provide a rapid, heightened response upon re-exposure to the same antigen
o Present antigen to T-cells
How to Properly Study for BIOD 171 Module 4:
1. Review Your Course Materials: Focus on:
o Lecture Notes & Videos: The primary source of exam content.
o Lab Manuals & Activities: Practical applications of concepts.
o Assigned Readings: From your textbook or modules.
o Learning Objectives/Outlines: Provided by your instructor. These tell you exactly
what you need to know.
2. Create Your Own Study Tools:
o Make flashcards for definitions (e.g., virion, capsid, virulence, phagocytosis).
o Draw diagrams of viral replication cycles (lytic vs. lysogenic) and immune
responses.
o Teach the concepts to a friend or study group.
3. Use Practice Resources Appropriately:
o End-of-Chapter Questions in your textbook are excellent for self-testing.
