Immunology and Disease Prevention Concepts

These flashcards cover key concepts in immunology, disease prevention, and related topics as presented in the lecture.

Bovine Viral Diarrhea (BVD)

An example of under reactions of the immune system.

Cytotoxic hypersensitivity

Involves the immune system being sensitized to another blood type.

Colostrum

First milk produced by mammals, rich in antibodies.

Acquired Immune Deficiency Syndrome (AIDS)

A condition characterized by the reduction in CD4 T cells.

Immediate allergic hypersensitivity

Marked by excessive IgE and eosinophils.

Delayed hypersensitivity

An immune response that can be tested using the TB test.

Autoimmune hypersensitivity

Involves the production of autoantibodies.

Edward Jenner

Known as the 'father of immunology'.

Adjuvant

An agent that enhances the immune response to an antigen in a vaccine.

Antiserum

Serum containing antibodies from another animal.

Passive immunity

Immunity provided by antibodies produced by another organism.

Biostatic

Refers to antimicrobial products that inhibit or halt microbial growth.

Disinfectant

A chemical used to destroy all vegetative microorganisms.

Antiseptic

A product used on living tissue to destroy microorganisms.

Sanitation

The reduction of pathogenic organism numbers to a safe level.

Broad-spectrum antibiotic

Antibiotic that affects a wide variety of bacteria.

Selective toxicity

The ability to harm microbes without damaging the host.

Pathogenesis

The development and progression of disease.

Reservoir

Source of organisms that cause disease, often animals.

Epidemiology

The study of disease patterns in populations.

Antigenic drift

Small mutations in viruses that may affect immunity.

Antigenic shift

A significant change in a virus that can lead to new strains.

Superinfection

A secondary infection that occurs on top of an existing one.

Pathology

The study of disease.

Etiology

The cause of the disease.

Quarantine

Isolation of new or returning animals to monitor for diseases.
