7) What are vaccines used for?
Case 1:
I am NOT considered a living organism because I am not made of
cells.
ANSWER IN YOUR NOTEBOOK:
1. WHO AM I?
2. Am I living or non-living and WHY?
3. HOW DO I REPRODUCE?
Case 2:
I can be round or bullet-shaped and I have a protein shell
called a capsid protecting my genetic information (DNA).
ANSWER IN YOUR NOTEBOOK:
1. WHO AM I? How do you know?
2. HOW do I infect a host?
Case 3:
I am a unicellular living organism with no nucleus.
ANSWER IN YOUR NOTEBOOK:
1. WHO AM I?
2. Am I a prokaryote or eukaryote, why?
3. Am I living or non-living and WHY?
4. How do I REPRODUCE? (HINT: Cells reproduce with mitosis…)
Case #4:
A girl is bitten by a dog. To prevent the possibility of rabies,
her doctor prescribes the rabies vaccine.
ANSWER IN YOUR NOTEBOOK:
1. What could the girl be infected with: a virus or bacteria?
How do you know?
2. What is a vaccine?
Case #5:
James’ throat has been killing him lately and he is starting to
feel hot. Upon further inspection, you find he is infected
with a prokaryotic, unicellular microbe that is growing and
reproducing through mitosis.
ANSWER IN YOUR NOTEBOOK:
1. What is he infected with virus or bacteria? How do you
know?
2. What would you use/prescribe? Why?
Case #6:
Maria is very concerned about contracting the chicken pox.
She wants to eliminate any possibility of getting the disease.
ANSWER IN YOUR NOTEBOOK:
1. What is chicken pox, virus or bacteria? How do you
know?
2. What would you use/prescribe to PREVENT chicken
pox? Why?
3. Are there medicines that get rid of chicken pox once
someone has the disease?
Case #7:
Mrs. McPherson hates being sick and there is NO way she is
getting the flu next year, what should she do to eliminate
the possibility?
ANSWER IN YOUR NOTEBOOK:
1. Is the flu a virus or bacteria? How do you know?
2. What would you use/prescribe? Why?
3. How does flu infect a host?
Case #8:
HIV can only survive in a body– it gets destroyed almost
immediately outside of a person. The reason for that is that
HIV cannot reproduce by itself; it uses human DNA to
reproduce. HIV implants its genetic information into the
healthy cell's DNA, which subsequently starts acting like a
virus-producing plant. Eventually, the exhausted cell dies,
but not before churning out multiple copies of the virus
ANSWER IN YOUR NOTEBOOK:
1. Is HIV a virus or bacteria? How do you know?
2. Why is HIV so hard to treat, once a person is infected?
Case #9:
Food poisoning, like Salmonella, can be prevented with
proper care and handling of food products. Bacteria related
food poisoning is the most common and can happen when
people eat food that was not cleaned or cooked properly.
ANSWER IN YOUR NOTEBOOK:
1. What is bacteria?
2. What would you use to treat food poisoning?
Case #10:
On vacation, Mr. Fleming was bitten by a mosquito. Upon
returning home he started to feel very tired, achy and is
running a fever. After taking a blood sample you discover
foreign DNA in his cells that are using her host cells to
replicate.
ANSWER IN YOUR NOTEBOOK:
1. What is she infected with virus or bacteria? How do you
know?
2. Can you treat her? Why or why not? What would you
use?
3. BONUS: What is the name for this disease spread by
mosquitoes?
