Microbiology Module Overview & Mock Exam
This module overview pulls together the core concepts from Lessons 1 through 3. Use it as a final pass before taking the cumulative mock exam.
Topics Covered
- Lesson 1 — Basic Science, Microbial Control & Lab Safety: cell classification, bacterial shape and arrangement, bacterial structures, viruses, bacteriophage and animal virus multiplication, microbial control terms, physical and chemical methods of control, staining techniques, susceptibility testing, handwashing, protective gear, equipment care, and specimen handling.
- Lesson 2 — Infection, Disease & Epidemiology: symbiosis, normal flora, opportunistic pathogens, portals of entry and exit, virulence, invasion, adhesion, colonization, evasion, toxins, infectious dose, infection patterns, reservoirs, contact, droplet, airborne, vehicle, bodily fluid, and vector transmission, HAIs, antimicrobial resistance, and prevention.
- Lesson 3 — Immune Response & Lymphatic System: innate and adaptive immunity, antigens, MHC I and MHC II, antibodies, immune organs, leukocytes, granulocytes, agranulocytes, lymphocytes, first, second, and third lines of defense, inflammation, fever, interferons, cytokines, complement, cell-mediated immunity, antibody-mediated immunity, active immunity, passive immunity, surveillance, investigation, and response.
High-Yield Review
| Concept | High-yield point |
|---|---|
| Eukaryotic vs. prokaryotic cells | Eukaryotic cells have a membrane-bound nucleus; prokaryotic cells do not. |
| Gram-positive vs. Gram-negative structure | Gram-positive bacteria have thicker peptidoglycan; Gram-negative bacteria have an outer membrane and larger periplasmic space. |
| Sterilization vs. disinfection | Sterilization eliminates all microbial life including endospores; disinfection destroys vegetative life but does not kill endospores. |
| Droplet vs. airborne transmission | Droplets travel less than 1 meter; airborne particles can travel more than 1 meter. |
| MHC I vs. MHC II | MHC I helps recognize self and target infected cells; MHC II presents foreign antigens to T cells. |
| Antibody function | Antibodies mark antigens for destruction but do not directly kill them. |
| Active vs. passive immunity | Active immunity forms memory cells; passive immunity uses outside-source antibodies and lasts only while those antibodies remain. |
Mock Exam
The quiz for this lesson is a cumulative 50-question mock exam. It mixes recall, comparison, and clinical or lab-safety application questions from the full Microbiology module.
