EXAMS WITH COMPLETE ACTUAL EXAM QUESTIONS
AND CORRECT VERIFIED ANSWERS/ ALREADY GRADE
A+ (MOST RECENT!!)
What are opportunistic pathogens? .....ANSWER.....Only affects
you when your immune system is trash, e.g those with HIV/AIDs
(Usually die of secondary infection)
What are prions? .....ANSWER.....No genome, proteins
Can cause disease
Can also cause normal proteins to change shape and become
new prions (if ingested)
*Mad cow disease
What are prion-associated diseases .....ANSWER.....1.
Creutzfeldt-Jacob Disease
,Page 2 of 78
2. Variant Creutzfeldt-Jacob Disease
3. Bovine Spongiform Encephalopathy (BSE, Mad Cow Disease)
4. Kuru
- All of them cause the brain to look like a sponge
- ALL cause cognitive impairment
How are viruses different than bacteria? .....ANSWER.....- Some
have envelopes, if they don't they're considered naked
- Submicroscopic infectious agents that have either DNA or RNA
- Capsid protects virus when it is NOT inside host cell (i.e.
Hanging onto the door knob)
What is bacteria? .....ANSWER.....Prokaryote
-W/o nuclei and no membrane-bound organelles
-Produce biofilm: Collection of bacteria on surface
-Contain RNA and DNA
,Page 3 of 78
-Bacteria with plasmids can give an "edge"; codes for resistance
to certain antibiotics
- Use hosts for food and shelter
Are most fungal infections on the surface of the body?
.....ANSWER.....Yes
What are fomites? .....ANSWER.....inanimate objects that can
spread disease such as a doorknob, clothing, countertop etc
What are zoonoses .....ANSWER.....diseaes of animals that can
spread to humans
How do pathogenic microbes get into the body?
.....ANSWER.....Depends on the microbe, but in general, they can
be ingested, inhaled or get in through vaginal fluid or semen.
What are virulence factors?
How do they allow bacteria to be pathogenic?
.....ANSWER.....Allow bacteria to be pathogenic
, Page 4 of 78
- Destroy some part of the host, making it easier to get in or
replicate
i.e. Lipase - digest oil on skin
Where do bacteria endotoxins come from?
What do they cause? .....ANSWER.....Endotoxins cause host
immunize reactions
What are bacterial exotoxins?
What do they do to host cells? .....ANSWER.....- Proteins released
by bacteria
- Damage or kill host cells
What is sepsis? .....ANSWER.....toxic inflammatory condition
arising from the spread of microbes, especially bacteria or their
toxins, from a focus of infection in the blood
If a word ends in itis, what does that mean?
.....ANSWER.....Inflammation, may or may not be due to infection
