Medical Microbiology - Chapter 1 Exam Questions
and Answers
1. Microbiology correct answers: the study of microbes (microorganisms) that can only be seen
well with a microscope
organism implies living - not everything in the microbial world is alive!
2. Bacteriology correct answers: the study of bacteria
3. Protozoology correct answers: the study of protozoans
4. Phycology correct answers: the study of algae (pools get algae, starts with a p)
5. Mycology correct answers: the study of fungi (think how mushrooms are fungi, starts with an m)
6. Virology correct answers: the study of viruses
7. Parasitology correct answers: the study of parasites
8. Pathology correct answers: the study of disease correct answers: causes, symptoms, cures,
etc.
9. Immunology correct answers: the study of how the body defends itself against invaders
10. Detrimental Aspects of microbe action (~10% microbes) correct
answers: Microbes cause correct answers:
1. disease/infection
2. food spoilage (typically bacteria/fungi)
3. structural damage (mold)
4. environmental damage (red tide)
11. Beneficial Aspects of microbe action (~90% of microbes) correct
answers: microbes have many ecolog- ical roles - they are the beginning of all food
chains/food webs.
Only some bacteria can undergo nitrogen fixation --> crop rotation that revolutionized
agriculture microbes account for 70% of earth's photosynthesis
microbes cause decay/decomposition (which is the ultimate recycling of matter back into the ecosystem)
12. Symbiosis correct answers: partnership between organisms
13. Mutualism correct answers: both partners benefit
1/
9
, 14. Commensalism correct answers: one partner benefits and the other partner is neutral
15. Parasitism correct answers: one partner (called the parasite) benefits and the other partner
(called the host) is harmed
16. Commercial/Industrial roles of microbes correct answers: microbes
are used for the production of many chemicals such as pharmaceuticals, alcohols, and
acids
microbes are important in food production
