MIC 130 Exam 1 questions with correct answers
isolation - Correct Answer-=
Define the germ theory of disease and describe the historical advances toward that
knowledge. - Correct Answer-Germ theory: Infectious diseases are caused by
pathogens
(germs are microbes/organisms that cause infectious disease, also known as a
pathogen)
Summarize how infectious diseases are different than other diseases - Correct
Answer-Infectious diseases are spread person to person, by vector, airborne, etc.
whereas diseases such as diabetes are not contagious
Recall whether treatment or vaccination is available for each group. - Correct
Answer-Fungi: no vaccine, just antifungal drug
Parasite: no vaccine, just anti parasitic drug
Bacteria: vaccines available for a few, almost all treated with anitbiotics
Virus: vaccines for many, antiviral drugs don't exist for most
Pathogen - Correct Answer-organism that causes disease
miasma - Correct Answer-a highly unpleasant or unhealthy smell or vapor
,- follow smelling air
- miasma was thought to be the reason for cholera (diarrhea disease from sewage
being dumped into river)
spontaneous generation - Correct Answer-Hypothesis stating that life could arise
from nonliving matter
-"we damp cool areas, toads will be born"
Koch's Postulates - Correct Answer-a sequence of experimental steps for directly
relating a specific microbe to a specific disease
1. microorganisms are isolated from dead animal
2. microorganisms grown in a culture
3. microorganisms identified
4. microorganisms injected into healthy animal
5. disease reproduce and isolated
6. microorganisms grown in pure culture
7. microorganisms identified
What are limitations?
- cannot be performed on humans
Infection - Correct Answer-microbe living in or on a host
Colonization/microbiota - Correct Answer-becomes part of microbiota
, Disease - Correct Answer-damage to the host (symptomatic)
True pathogen - Correct Answer-capable of causing disease in healthy persons,
infects anyone
Opportunistic Pathogen - Correct Answer-infects host with weakened immune
system (compromised)
Vaccine - Correct Answer-
Anti-microbial drugs - Correct Answer-
Louis Pasture (1822-1895) - Correct Answer-- disproved spontaneous generation
- developed vaccines
Bacteria - Correct Answer-- prokaryotic
- very small, simple cell structure
- inhabit almost all areas of the earth
- major involvement in environmental places
- most harmless, some beneficial
- some are pathogens
Prominent bacterial diseases:
- TB, plague, cholera, typhoid fever, typhus, strep throat, some cause diarrhea,
respiratory infections, meningitis, STIs
