Answer:
I really hope this helps! I’m doing something similar in my medical micro class and I’m swamped in that so I understand how you feel.
1.Infectious diseases are caused by
C.pathogens.
2.Give an example of a disease caused by a
Protozoan.
Malaria.
3.Why is it not a good idea to share a drinking glass
with someone?
If the water in a drinking glass or plastic bottle is shared with others, the risk for bacteria, viruses and intestinal parasites increases.
4.Critical Thinking Do you think that all
microorganisms are pathogens? Explain your
Answer.
This needs to be in your words but I’ll make it easier for you:
No I do not believe that all microorganisms are pathogens. This is because bacteria are microorganisms and not all bacteria are pathogens.
Section 2
5.White blood cells that carry out most of the
immune system’s functions are called
B. lymphocytes.
6.What role do phagocytes play in inflammation?
Phagocytes engulf and destroy pathogens.
7.What types of cells produce antibodies?
B cells! Each B cell produces a single species of antibody, each with a unique antigen-binding site. When a naïve or memory B cell is activated by antigen (with the aid of a helper T cell), it proliferates and differentiates into an antibody-secreting effector cell.
8.Explain how a vaccine can make you immune to a
particular infectious disease.
Vaccines contain a harmless form of the bacteria or virus that causes the disease you are being immunised against. The bacteria or virus will be killed, greatly weakened, or broken down into small parts before use in the vaccine so that they can trigger an immune response without making you sick.
9.Critical ThinkingHow does your immune
system “remember” a particular pathogen?
B lymphocytes are the cells of the immune system that make antibodies to invading pathogens like viruses. They form memory cells that remember the same pathogen for faster antibody production in future infections. It’s kind of like a database.
10.Critical ThinkingMultiple sclerosis is a disease
in which T cells attack parts of the central nervous
system. How arethese T cells acting differently
from normal T cells?
Killer T cells attack healthy body cells. Normal T cells attack body cells with pathogens

11.Antibiotics areusually prescribed for diseases
caused by
d.bacteria.
12.What part of the body does hepatitis affect? What
Liver, viral hepatitis is most commonly caused by hepatitis A virus (HAV), hepatitis B virus (HBV), and hepatitis C virus (HCV).
13.Why is it important to make su
type of pathogen causes hepatitis?
re that your
immunizations are current?
For children at least-vaccines for preventable diseases is essential. If a group of babies and young children fall behind on their vaccines, these diseases will have an opportunity to reemerge, causing outbreaks. It could even cause a community spread.
14.Critical ThinkingMore people get the flu
during the winter months than at any other time
of year.Why do you think this is true?
Personally I believe it is because people tend to stay inside together. You have people swapping germs and reusing items.
Section 4
15.Anepidemic refers to a disease that
a.affects very b.affects many people
few people.in one area.
c.is caused by d.doesn’t spread.
bacteria.
The question is a little mixed up but here: Epidemic refers to an increase, often sudden, in the number of cases of a disease above what is normally expected in that population in that area. Outbreak carries the same definition of epidemic, but is often used for a more limited geographic area.
16.Explain how antibiotic resistance could lead to a
bacterial disease epidemic.
If the disease changes and mutates the disease will spread rapidly without a cure.
17.Critical ThinkingDuring the SARS outbreak of
2003, the World Health Organization issued a
warning against traveling to countries where SARS
was present. Explain why this warning was issued
So that the illness would not be spread by visitors into their own countries and create a pandemic.
