A vaccination
Management practices are
Stress & sanitary measures
Antigen or antibodies of disease who’s causative agents have been identified is known as
Biological Agents
Preparation of killed, living or attenuated microorganisms introduced into the body to produce immunity to a disease is known as a
Vaccine
Name 5 forms of vaccines
Living virus Attenuated/Modified Killed Bacterins Toxoids
This vaccine does not cause healthy animals to contract a disease. Its used to stimulate antibody production against a virus
Living Virus Vaccine
This vaccines organism will stimulate antibody formation without producing disease symptoms. Growth and subsequent change in an organism in an animal
Attenuated/Modified
This vaccine uses Physical or chemical agents are used to destroy a pathogenic organism
Killed Vaccine
This vaccine suspensions of killed pathogens bacteria used to stimulate immunity
Bacterins
This vaccine is a physical or chemical inactivated toxin
Toxoids
Viral Vaccines
Must be propagated in living tissue. Originally grown in host animal. Grown in chick embryos. Currently propagated in tissue cultures
Bacterial Vaccines
Propagated in many environments. Weak antigens
Bacterial Vaccines: weak antigens (adjuvant is)
Acts to increase favorable immunity by slowing down absorption
Anti-Serums
Hyper-immune animal passive immunity. Large volume
Hyperimmune Goblins
Fractionation Process, yields a product which is chemically pure, bacteriologically sterile suspension of pure gamma globulins
Name the 4 modes of germicidal action
Oxidation
Coagulation
Chemical reactions
Removal of water or elements that form water
What is oxidation
Oxygen combining chemically with germ or actually oxidizes or burns it
What is coagulation
Fluid state substance forms a clot
What is chemical reaction
Germs form new complex compounds which are free from harmful qualities
Desirable characteristics in germicides
Low price
Effective at ordinary temps
Organic products
Effective after it has been diluted with water
