died and almost one million pigs had to be euthanized to control the outbreak. Since this infectious agent
could be transmitted from pigs to humans, it is best described as:

,Question:
7. A woman reported to a clinic with nausea, abdominal pain, fatigue, and jaundice (yellowing of the eyes
and skin). Her symptoms began two weeks after returning from a trip to Hawaii where she had eaten sushi
that included raw scallops at a popular restaurant. She had signed up for a rewards program associated with
the nationwide sushi chain, and had been notified via the app on her smartphone that she may have been
exposed to a fecal-orally transmitted infectious agent. She most likely was exposed to and now had
symptoms of infection with a microbe whose portal of entr was:
Answer:
digestive tract
Question:
8. Influenza is primarily a respiratory disease, and is not the same as the "stomach flu", although some
people, especially children can experience stomach symptoms during a flu infection.
Answer:
True
Question:
9. It is possible for individuals infected with influenza to transmit the virus to others one day before
showing symptoms and as long as five days after becoming ill.
Answer:
True
Question:
10. The influenza vaccine consists of killed virus or weakened virus, but neither form can give you a flu
infection.
Answer:
True
Question:
11. Lyme disease is caused by the bacterium Borrelia burgdoferi and is found in certain ticks seasonally
every year in parts of the United States where the tick is found. Ticks feed on deer mice, where they may
pick up the bacterium, then, if an unlucky person who is hiking or outdoors picks up the infected tick, they
may become infected when the tick injects the bacterium while taking a blood meal. Lyme disease and the
transmission via the mouse to tick to human is best summarized as:
Answer:
Zoonotic, biological vector
Question:
12. The helper T cells or TH are part of the humoral immune system, and they can differentiate into plasma
and memory cells.
Answer:
False
Question:
13. The helper T cells or TH are part of the cellular immune system, and they are also known as CD4 cells.
Answer:
True
,Question:
14. This virus is vaccine-preventable.
Answer:
Hep A Rubella
Question:
15. IgM is an antibody that is a monomer and has two Fab, where Fab is the antigen binding portion of the
antibody.
Answer:
False
Question:
16. IgG is an effector cell of the cellular immune system.
Answer:
False
Question:
17. This microbe is transmitted via unsanitary conditions via the fecal-oral route and leads to symptoms of
fatigue, lack of appetite, abdominal pain, and jaundice. Treatment of this infection typically consists of a
vaccination (if a person is unvaccinated and was exposed in the last 2 weeks), rest, appropriate nutrition
and fluids.
Answer:
Hepatitis A virus
Question:
18. The period of time when we are at the beginning of an infection with a pathogen, and just beginning to
show mild signs or symptoms is the period of convalescence.
Answer:
False
Question:
19. The period of time when we are harboring an infectious agent, and beginning to show mild signs or
symptoms is the prodromal period.
Answer:
True
Question:
20. A dairy farmer reported to the clinic with a fever, myalgia (muscle pain), extreme fatigue, and
abdominal pain. The clinician was concerned because the patient was pregnant, and her fetus could be at
risk, and she could be at risk of developing a chronic form of the disease of the intracellular bacterial
pathogen. The patient reported that her cattle had positive for the bacterium. The clinician looked up the
infectious agent and found that in one study using mice, 2,032 bacteria were enough to kill 50% of the
mice. This was reported as the
Answer:
idk but not a and c
, Question:
21. A person who is a carrier of Streptococcus pneumoniae, carries it in their nose and throat, and may
transfer pathogens without realizing it to vulnerable individuals.
Answer:
True
Question:
22. A pathogen invades a new host and causes disease. Within two weeks, effector molecules are produced
which are able to bind to the pathogen and coat the microbe so that it cannot adhere to mucosa. The
effector molecules are ___antibodies___ and when they coat the pathogenic microbe and prevent adhering
to the mucosa, this is called ___antigen___
Answer:
only 2 /4 antibodies antigen
Question:
23. Which of the following is a cell that destroys abnormal or virally-infected cells by releasing perforin
and granzymes?
Answer:
only 1/2 Cytotoxic T lymphocyte
Cytotoxic T cells
Question:
24. Which infectious agent is a worm that can be transmitted through contaminated and undercooked food?
Answer:
Paragonimus westermani
Taenia saginata
Question:
25. This microbe is an oncogenic virus, and lowers the ability of the host to fight infectious disease agents
in the body. The virus attacks CD4 cells (helper T cells) and since these cells are so critical for the adaptive
immune response, an individual who is not treated for the infection will succumb to infectious agents that
would normally be destroyed by a functional immune system. This virus is
Answer:
idk but not kaposi
Question:
26. This microbe has been associated with bats, and humans who become infected may have
respiratory-associated symptoms and encephalitis. This microbe is:
Answer:
Nipah virus
Question:
27. This microbe can be latent in humans, remaining in the human host cells for a long time without
producing visible infection. Click any/all microbes that can become latent in humans.
Answer:
Varicella zoster virus
