Module 9 poll and assignment Flashcards
The innate immune system is composed of:
a. barrier defense, phagocytes and the complement system
b. both barrier defense and phagocytes
c. several non-specific mechanisms that include barrier defenses, phagocytes, the complement system, inflammation and fever
d. only phagocytes
e. only barrier defense
c.
What kind of lymphocytes would you expect to be over-represented at the site of viral infection?
a. basophiles
b. macrophages
c. neutrophils
d. natural killer cells
e. eosinophils
d.
If you are designing a vaccine and want a strong antibody response, what type of T cells would you target to ensure strong B cell activation?
a. TH1 cells
b. TH2 cells
c. TH17 cells
d. Treg
e. Cytotoxic T cells
b.
When comparing innate immunity and adaptive immunity, which statement is true?
a. Innate immunity is involved in the production of antibodies, whereas adaptive is mediated by T cells and B cells
b. Innate immunity is the first and second line of defense that prevents entry and spread, where as adaptive immunity is the third line of defense that provides a specific response to dangers
c. Innate immunity is the primary player of the immune system, whereas adaptive immunity is the coordinator of the different branches of the immune system
d. Innate immunity is mediated only by the skin and mucosal barriers, whereas adaptive immunity is only mediated by immune cells
b.
What is a major disadvantage of toxoid vaccines compared to other vaccine types?
a. It does not provide immunity
b. protective epitopes are altered
c. It cannot be used to vaccine immunocompromised individuals
d. It does not protect against infection
d.
why would a fishmonger develop fish tank granuloma (i.e. skin infection caused by mycobacterium marinum)
a. the bacteria used their flagellum to dig a whole in the skin
b. cuts on the skin remove a layer of the innate protection and allowed entry of the bacterial pathogen
c. The slime layer of the skin was dissolved by salt water
d. Macrophages accumulated under the skin in response to a traumatic shock from a fish bite
b.
How can the immune response recognize pathogens during their first encounter?
a. pathogen-associated molecular patterns recognized by patter recognition receptors
b. pathogen-associated molecular patterns recognized by the major histocompatibility complex
c. immunogens recognized by the major histocompatibility complexes
d. immunogens recognized by pattern recognition receptors
a.
Why would a fishmonger develop granuloma in response to mycobacterium marinum infection
a. Aggregation of macrophages and other immune cells formed in response to chronic inflammation
b. mycobacterium marinum infection caused cancerous cells
c. Mycobacterium marinum formed a biofilm full of mycolic acid
d. capillary walls aredilating and allowed mineral deposits
a.
The acquired immune system is characterized by
a. two different branches: humoral immunity and cell-mediated immunity
b. the ability to create a memory of previous threats
c. the ability to discriminate between danger and non-danger
d. the ability to recognize many different types of danger
e. all of the above
f. none of the above
e.
