• This is a multiple-choice practice question exam, with 64 questions worth 64 points in total.

Question 1

• General mechanisms inherited as part of an animal's innate structure are referred to as Nonspecific immunity.

Question 2

• Staphylococcus epidermidis is a bacterium associated with skin infections.

Question 3

• The mucociliary escalator protects the lungs from microorganisms.

Question 4

• Bacteria are the targets of lysozyme.

Question 5

• Phagocytosis leads to destruction of engulfed pathogens through lysosomal mediated hydrolysis.

Question 6

• Tears protect the eyes by flushing and lysozyme.

Question 7

• The target of T cells is intracellular viruses, cancer cells, and transplant tissue.

Question 8

• Secreting an antibody is an exclusive function of the humoral immune response.

Question 9

• The immune system differentiates between self and non-self antigens.

Question 10

• When botulism antibodies are produced in a horse and given to a human, this is an example of artificially acquired passive immunity.

Question 11

• Vaccination is an example of artificially acquired active immunity.

Question 12

• Bordetella pertussis uses an acellular/subunit vaccine.

Question 13

• Attenuated vaccines utilize weakened pathogens.

Question 14

• Fever is not a characteristic of inflammation.

Question 15

• The transfer of antibodies in colostrum is an example of naturally acquired passive immunity.

Question 16

• An epitope is the part of the antigen that induces the formation of a specific antibody.

Question 17

• Neutralization, as an antibody manifestation, means a virus is unable to attach to its host cell.

Question 18

• The MMR vaccine protects from measles, mumps, and rubella.

Question 19

• Antibodies are not typically used in a vaccine that produces active immunization.

Question 20

• The human vaccine for Rabies is composed of an inactivated whole-agent vaccine.

Question 21

• A major reason why it is difficult to treat viral infections with chemotherapeutic agents is that viruses use the metabolic machinery of their hosts, which limits selective points of attack.

Question 22

• Varicella-zoster is the virus that causes chicken pox.

Question 23

• Rubella is the virus that causes German measles.

Question 24

• Women of child-bearing age should be vaccinated against German measles.

Question 25

• Contaminated blood and blood products are the typical mode of transmission for Hepatitis C.

Question 26

• Legionella pneumophilia can be found in air conditioning systems.

Question 27

• Surgical removal of tissue is how gangrene is treated.

Question 28

• Infection with Neisseria gonorrhoeae may lead to pelvic inflammatory disease.

Question 29

• Francisella tularensis is transmitted to humans through insect bites, contact with infected tissue, and inhalation.

Question 30

• Canned beans are not involved in the transmission of salmonellosis.

Question 31

• The secondary stage of syphilis is characterized by a skin rash.

Question 32

• The disease anthrax is caused by bacteria belonging to the Bacillus genus.

Question 33

• Yersinia pestis causes bubonic plague.

Question 34

• Streptococcus mutans is involved in the development of tooth decay.

Question 35

• Tinea pedis is associated with the foot.

Question 36

• Cryptococcus grows in yeast form in humans.

Question 37

• Pigeon droppings are associated with infections of Cryptococcus neoformans.

Question 38

• Clostridium genus produces a potentially lethal foodborne infection.

Question 39

• Claviceps purpura makes ergot.

Question 40

• Giardiasis is a waterborne disease caused by a eukaryote.

Question 41

• Staphylococcus aureus is responsible for the most common form of food poisoning.

Question 42

• Clostridium botulinum is the biggest risk with food poisoning in home canned foods.

Question 43

• The site of the infection and the number of bacteria introduced into the infection influence the incubation period for a rabies virus infection.

Question 44

• Exposure to cold can reactivate a latent Herpes simplex 1 infection.

Question 45

• Encephalitis is a severe complication associated with measles.

Question 46

• Bordetella pertussis causes a disease characterized by the catarrhal, paroxysmal, and convalescent stages.

Question 47

• Chlamydia does not cause Pneumonia.

Question 48

• Tuberculosis and Leprosy are caused by Mycobacterium sp.

Question 49

• Canadians are routinely vaccinated for Haemophilus influenzae.

Question 50

• Fungal skin diseases are called Dermatomycosis.

Question 51

• Psitticosis form of pneumonia is most likely to be found in pet store employees.

Question 52

• Streptococcus pyogenes causes Rheumatic fever.

Question 53

• Development of a vaccine against rhinovirus is difficult because they are many serovars (antigenically distinct) strains.

Question 54

• Croup causes an obstruction of the larynx.

Question 55

• Too little oxygen in the blood causes cyanosis.

Question 56

• Epstein-Barr virus early childhood infections are usually asymptomatic.

Question 57

• Infections with Toxoplasma gondii are most severe during the first trimester of pregnancy.

Question 58

• Russia had an increase in Diphtheria due to a breakdown in public health measures.

Question 59

• Sequelae is a term used to describe adverse signs that follow a disease.

Question 60

• Mycobacterium tuberculosis is not killed by phagocytes.

Question 61

• Borellia burgdorferi causes Lyme's Disease.

Question 62

• Relenza is used to relieve the symptoms of Influenza.

Question 63
