Lecture 7

Question 1

most important method of prophylactic method

Answer 1

immunoprophylaxis

Question 2

goal of immunisation

Answer 2

induce immunity

Question 3

vaccine definition

Answer 3

suspension of live (usually attenuated) or inactivated microorganism to induce immunity and prevent infectious diseases

Question 4

vaccination definition

Answer 4

physical act of administering any vaccine or toxoid

Question 5

immunisation definition

Answer 5

process of being made immune or resistant to an infectious disease

Question 6

MDA

Answer 6

horse pig cow dog and cat’s MDA cannot pass through the placenta

so they need to ingest colostrum within 24 hrs after birth and the colostrum decreases oveer tie

it’s absorbed in SI, goes to lymph then circulation and then provides immunity

must ingest during 1st 2 hours of life; 6 hours after birth they’re detectable

Question 7

passive immunity

Answer 7

• transfer of antibody produced by one animal to another
• natural (colostral0
• artificial (passive immunisation0
• passive immunisation = transfer of antibodies to an unprotected individual for the prevention or treatment of disease

adverse reaction = hypersesntiivty
protection = short lasting

Question 8

types of vaccine

Answer 8

infectious
- attenuated
- heterologous
- recombinant

non-infectious
- whole pathogen
- subunit
- conjugated
- toxoid
- DNA/RNA

Question 9

type 1 hypersensitivity

Answer 9

• IgE
  immediate hypersensitivity
  dogs present with skin and general circulation signs
  cats have gastrointestinal and respiratory signs

Question 10

type 2 hypersensitivity

Answer 10

production of IgG and IgM antibodies binding to specific cell surface antigens and producing cytotoxicity

Question 11

type 3 hypersesntivity

Answer 11

develop from acute inflammation triggered by presence of immune complexes in tissues

Question 12

type 4 hypersensitivity

Answer 12

involves cell-mediated immune responses
take more than 12 hours to develop
