MICROBIOLOGY BASIC QUESTIONS
BY DR. ALEXANDER MENDIETA
1. Bacterial Structure and Function:
- What are the main components of a bacterial cell wall, and how do they contribute to
bacterial structure?
- Explain the difference between gram-positive and gram-negative bacteria.
- How do bacterial flagella contribute to motility?
2. Bacterial Growth and Reproduction:
- Define binary fission and describe the stages involved in bacterial cell division.
- What factors influence bacterial growth, and how do they impact microbial populations?
3. Viral Structure and Replication:
- Describe the structure of a typical virus.
- Explain the differences between the lytic and lysogenic cycles in viral replication.
4. Fungal Classification and Characteristics:
- Differentiate between yeasts and molds in terms of structure and reproduction.
- What are the main features that distinguish fungi from other microorganisms?
5. Antimicrobial Agents:
- Describe the mechanisms of action of antibiotics, antivirals, and antifungals.
- What is the difference between bacteriostatic and bactericidal agents?
6. Microbial Pathogenesis:
- Explain the concept of virulence in microbial pathogens.
- Describe the stages of microbial infection, including adherence, colonization, and invasion.
7. Host-Pathogen Interactions:
- Discuss the host's immune response to bacterial and viral infections.
- How do pathogens evade the host immune system?
8. Microbial Diseases:
- Provide examples of bacterial, viral, and fungal diseases, and discuss their symptoms and
modes of transmission.
- Explain the concept of opportunistic infections in immunocompromised individuals.
9. Microbial Control and Sterilization:
- Describe different methods of microbial control, including physical and chemical methods.
- What is the difference between disinfection and sterilization?
