What does the immune system do?

Eliminate foreign substances introduced to the body to prevent harmful effects

1

What are six antigenic substances?

Bacteria, viruses, toxins, transplanted tissue, pollen, food protiens

2

What are the two components of the immune system?

Nonspecific and specific immune system

3

What does the non specific immune system do?

Prevents initial invasion by the antigen by using physical barriers and phagocytosis

4

What does the specific immune system do?

Controls the humoral immune system and the cell mediated immune response

5

What does the humoral immune system do?

Involves the production of AG specific antibodies by B-lymphocytes

6

What are six antibody classes? (IGAME)

IgI
IgG
IgA
IgM
IgE

7

What removes the extrasolar Ag's?

Antibodies

8

What does the cell mediated immune response do?

Involves the production of AG specific T-lymphocytes

9

What is immunization?

The administration of an AG to induce resistance to infection

10

How can immunization be achieved? 2

Exposeur to infectious disease

Vaccination

11

What are three types of vaccines?

Killed/inactivated

Modified live/attenuated

Recombinant/genetically engineered

12

How can temporary immunization be achieved?

By antibody administration through passive immunity or immunoglobulin injection

13

What is anaphylaxis?

Binding of an AG to IgE covered mast cells or basophils causing them to release chemical mediators like histamine

14

What are five possible Ag's for anaphylaxis?

Vaccines
Drus
Pollens/molds
Food ingredients
Insect bites

15

What are 7 symptoms of anaphylaxis?

Shock
Hives
Nasal/ocular discharge
Asthma
V
D
Dermatitis

16

What are autoimmune diseases?

Antibodies are formed against the animals own cells causing destruction

17

What are for examples of autoimmune diseases

Autoimmune hemolytic anemia
Autoimmune thrombocytopenia
Pemphigus
Myasthenia gravis

18

What is immunodeficiency?

Lack of the immune system components to provide immunity

19

What is an example of immunodeficiency?

Combined immunodefficiency in horses

20

Most diagnostic tests are based on what for the immune system?

Based on the humoral immune systems respone to AG

21

What is serology?

The science of detection and measurement of abs or Ag's.

22

What are three types of serologic tests for infectious diseases?

Enzyme linked immuno sorbet assay
Latex agglutination
Immuno diffusion
